Description

[0002] Agricultural chemical composition comprising pigments [

The present invention relates to an agricultural chemical composition, particularly to an agricultural chemical composition to which a pigment is added

Pesticides are drugs used to eliminate germs and pests that harm agricultural products, livestock and forest products, and to protect plants and plants. There are fungicides, herbicides, insecticides and growth regulators. Nowadays, it is considered to be a pesticide, and it is included in the pesticide to parasitize the body of the pest and suppress the generation of pest.

Pesticides that can be used practically should be effective in small amounts, have no damage by drugs, and should be low in livestock and human toxicity. Also, there is no damage to insects or beneficial insects. However, pesticides are mostly white powders, and when they are burned in water, they are colorless and odorless and can not distinguish whether pesticides exist or not, and there is a possibility of causing damage to livestock or people. For example, the liquid chlorine-based endosulfan liquid was transparent but did not intentionally cause an addictive accident because it gave off a bad smell. However, in case of pesticide which is a white powder, it was confused with wheat flour, and when an accident such as an agrochemical pesticide was a problem, pesticide powder was mixed with a gray powder which can be distinguished from flour and edible powder. The present invention also relates to a method for detecting residual insecticides of fruit and vegetables by using acetylcholine esterase (AChE), which is capable of rapidly and economically A method is known for preventing the commercialization of fruits and vegetables contaminated with residues by detecting residual insecticides.

The type of pesticide and residual toxicity, http://poiema.or.kr/xeboard/257852011.04.29, patent application No. 2004-0002416

Pesticides are used inevitably to prevent fruit, grain or vegetables from being damaged or deteriorated by insect pests, and contain harmful substances to animals such as humans and livestock. Therefore, Grains, vegetables, etc. can be harmful to humans if they are ingested, and even when used as feed for livestock, feeding the pesticide-bearing plants can cause damage to the livestock.

The pesticide has a half-life, so it is said that the possibility of second poisoning decreases after a certain period of time after spraying the medicines. However, this half-life is measured based on the spraying standard. When the second and third spraying are carried out, There is also doubt as to whether the results can be applied.

In order to minimize such damage, the present invention is characterized in that a pigment is added to a pesticide sprayed with a liquid (pesticide aqueous solution) to a grass used as a feed for human eating or livestock such as fruits, vegetables and grains, It is possible to confirm that the pesticide added with this pigment has been washed well when wiping fruits and vegetables and to minimize the damage of people or livestock caused by pesticides by making use of the pesticide- .

The present invention is a pesticide composition to which a pigment is added. Particularly, the present invention relates to a liquid pesticide composition to which a pigment is added.

The pesticidal composition of the present invention provides a liquid pesticide composition containing pesticides and pigments. Preferably an agricultural chemical composition comprising agricultural chemicals and an edible pigment.

The pesticidal composition of the present invention is prepared by dissolving the pesticide and coloring matter of the powder in water.

The pesticidal composition of the present invention is sprayed on vegetables or fruits in a general manner and is visually recognizable and is removed from vegetables or fruits by a general washing method, and the presence of the pesticidal composition is visually confirmed.

The liquid pesticide composition of the present invention is characterized in that the weight ratio of the pesticide to the pigment powder is 1: 1 to 1:10.

The liquid pesticidal composition of the present invention provides a liquid pesticide composition characterized in that the particle size of the pigment is 10 nm to 3 탆, preferably 50 nm to 2 탆, more preferably 100 nm to 1 탆.

The liquid pesticide composition of the present invention provides a liquid pesticide composition in which the pesticide is selected from an insecticide, a bacterium, a fungicide, a herbicide, an acaricide, a nematicide, a fungicide, or a plant growth regulator.

The liquid pesticide composition of the present invention further comprises a padding agent or an electrodeposition agent.

In the present invention, the pigment is defined as follows.

Dyes are not solutions but fine powders, used in paints, printing inks and plastics. Dyes are organic or inorganic materials. Organic dyes generally have a clear color and longer life than inorganic dyes. Pigments extracted from natural sources have been used for centuries, but most of the pigments used today are synthesized. Synthetic organic pigments are made from coal tar and various petrochemicals. Inorganic pigments are produced mainly from relatively simple chemical reactions such as oxidation reactions or from natural sources as earths.

The pigment added to the pesticidal composition of the present invention preferably has the following properties.

1) The use of natural food colors extracted from plants can minimize environmental damage. It is advisable to use food coloring even with synthetic pigments.

2) It is preferable that discoloration is not caused by sunlight for a certain period of time, preferably 6 months to 1 year, and it is preferably discolored or decomposed by sunlight after a certain period of time.

3) In case of green vegetables or various colored fruits, coloring with clear complementary effect is used. In case of kiwi fruit such as kiwi, use of green coloring can minimize disgust at the use field such as farms.

4) In general, when pesticides are applied as a liquid, pesticides contain agents that make the pesticides easily adhere to the plants, such as surfactants or electrodeposits, so that the pigments must be attached to the plants to the same degree as the pesticides. It is more suitable for the purpose of the present invention because it can perform a complete cleaning even if the sticking power of the pigment is slightly better than that of the pesticide.

5) The pigments should not be transferred to the surface or the inside by attaching to fruits, vegetables or grains. Usually, the vegetables, fruits, and grains that we eat usually have a cuticle layer on the surface, so that the pigment does not easily migrate to the surface of fruits, vegetables, or grains. However, even if it happens to some extent, The possibility of pesticide penetration can be minimized if the washing is performed to remove the pesticide.

6) If the amount of pigment is too high in the pesticide to which the pigment is added, it may interfere with the photosynthesis by the pigment, so it is necessary to quantify the amount of the pigment so that it can be discriminated from the naked eye without damaging the photosynthesis. The appropriate amount of the pigment may vary depending on the crop to which the pesticidal composition of the present invention is applied, particularly the color of the crop. It is preferable that the ratio of the weight of the pesticide powder to the weight of the pigment powder is 1: 1 to 10: 1. More preferably from 1: 3 to 1: 7, or from 1: 3 to 1: 5.

7) In order for the pigment to be evenly distributed, the dispersibility should be good so that it can be evenly distributed in the liquid pesticide. Therefore, if the particles of the pigment are too thick, they should not settle down. Even if the particles are too small, the pigment particles may be aggregated due to cohesion between the pigment particles. Generally, the currently produced food coloring is very small, but not so large as to coalesce, because it must be well mixed with food. Therefore, the size of the pigment is approximately 10 nm to 3 탆, preferably 50 nm to 2 탆, more preferably 100 nm to 1 탆, and particularly preferably similar to the particle size of the pesticide used as the pesticide powder.

The composition of the present invention may employ pesticides generally used in agriculture.

The kinds of pesticides can be variously divided according to the following classification criteria. Depending on the intended purpose, it may be used as an insecticide, a bactericide, a herbicide or the like. Depending on the chemical composition, it may be an organophosphorus, an organic chlorine system, a carbamate system, a pyrethroid system, , Granules, granules, and fumigants. According to the ecological toxicity criteria, the World Health Organization distinguishes itself as toxic, very toxic, usually toxic, and low toxic.

This classification system is fluid, and classification can be changed according to new functions and changes in form. Pesticides, which have been mainly studied in relation to health among various pesticides, are pesticides, fungicides and herbicides as synthetic organic medicines.

The present invention is a pesticide composition comprising all of the pesticides used in the classification according to the formulation of the multinomial formulation and sprayed on the part directly consumed by us, such as fruit, vegetables, and grains,

Pesticide is a chemical pesticide used to control diseases, pests and weeds that occur during the cultivation and storage of crops, biological pesticides, growth regulators used to promote and inhibit the physiological functions of crops, Supplements and so on. In a broad sense, pesticides also include fertilizers and all medicines used to prevent damages caused by plants and animals from disinfection of soil, disinfection of seeds, germination to fruiting, storage, etc. in agricultural management.

According to the action effect of pesticides, there is a disinfectant for the control of plant fungi, a bacterium for controlling plant bacterium, an insecticide for insect pest control, an acaricide for pest control, (Nematodes), killing nematodes, killing weeds, and killing mice. In addition, there are two types of killers:

Pesticides are prepared and used as powders, granules, liquid preparations, fumigants, smokers, and aerosols. Specifically, the granule is in a granular form, the powder is in the form of a pesticide, the powder is in the form of a pesticide, the water-soluble agent is a water-insoluble pesticide in the water, the water-soluble agent is a water-soluble pesticide dissolved in water, Pesticides and fungicides are used in the form of pesticides, fungicides are sprayed in the form of feces, pesticides and fumigants are spread in the air. And the coating agent includes an agrochemical agent used in such a manner as to be applied or attached like ointment or paste.

A germicide is a pesticide that has the effect of killing microorganisms or inhibiting growth in a broad sense. In general, there are disinfectants such as phenol, water, cresol, flocculent, chloralkal, formalin, alcohol, creosote soap, hydrogen peroxide, etc., which are known for home use. This includes antibiotics with antimicrobial properties. In the narrow sense, fungicides are fungicides, so-called medicines that kill fungi, and include medical disinfectants that treat skin diseases such as athlete's foot, and pesticides that are used to control fungal diseases that cause serious damage to plants, Fungicides are becoming the mainstay. The fungicide is applied to the plant during the cultivation of the crop or is treated in other seeds and soil.

Most of the currently used fungicides belong to protectant fungicides which have a preventive effect, and they are generally sprayed on the plant as a powder or solution. These fungicides do not penetrate the plant cuticle and do not migrate in the plant. However, the systemic fungicide, which has not only the recently developed protective effect but also the therapeutic effect, is absorbed through the roots, leaves and seeds and moved into the plant .

It is distinguished as an eradicant, a protectant, or a curative disinfectant depending on the action mechanism of the disinfectant. However, since the fungicide can not be strictly distinguished according to the effect, it can be divided into chemical structures as follows.

① Inorganic disinfectant: Bordeaux solution, lime sulfur mixture, etc. are available, but they are weak and usage is decreasing because of residual problem.

② Organic Mercury Agents: In Korea, since 1954, mainly for the control of rice blast fungi, benthic acid has been used, but since 1972, it has been used only for seed disinfection because of residual toxicity.

③ Dithiocarbamate: Originally developed as a curing agent for rubber, the disinfection effect was discovered, and the development of a pure organic synthetic disinfectant became full-fledged. This fungicide has a wide range of effects, and it is a great advantage that it has good affinity with plants as compared with copper and emulsifiers. It is used in the control of various diseases that form spots on leaves in the cultivation of fruit trees, flowers and vegetables. Daisen 45, Genev, Maneb, Propineb, and Georam.

④ Phthalamide agent: It has less harmfulness to crops and exhibits good pharmacological effects, including captains, capitol (dipolatan), and pollen.

⑤ Bendimidazole: Benomil (Benerate) has been used in large quantities since it was developed as a permeable fungicide in 1967. Thiophanate ethyl (topsin) belongs to this group and is used as a leaf spraying agent, a seed disinfectant, a soil disinfectant and so on.

⑥ Triazole: It is a widely used penetrating disinfectant which is triadimefon (baritone), tricalcium (beam) etc. and is effective for controlling powdery mildew, rust and blast.

⑦ Other Organic Fungicide: Metal Lacquer (Lidomill) is effective for preventive effect, therapeutic action, penetration action, and prevention of pestilence and pestilence. Hymexazol, kitazin (IBP), edifenphos and isoprothiolane are used for rice cultivation.

(8) Agricultural antibiotics: Antibiotics produced from soil microorganisms such as actinomycetes are used for cultivation of crops. Streptomycin, ciclohexamide, blasticidin S, carassomycin, polyoxin, validamycin, and the like.

Acaricide is an agent that selectively kills mites. Organic synthetic insecticides contributed greatly to mite control, which is as big as insects in vegetable, fruit and flower cultivation. Organophosphate insecticides such as parathion, malathion and EPN have insecticidal activity against adults of mites but have little salinity and low practicality as acaricide.

Some acaricides have insecticidal properties against insects, but they are characterized by selective resistance to mite. The conditions under which Salvius should have are:

① It should be effective against eggs as well as adults.

② Because the period of occurrence of mites is long, the residual effect must be long.

③ Only mites should have selective effect.

④ It should be effective against several mites.

⑤ There should be no harm to crops.

Salicylates, widely used in mite control, include dicotol, tedion (tetraditon), chlorofenson, bromopropylate, chinomethionate, and azocyclotin.

A nematocide is an agent that kills nematodes that are parasitic in the soil or plant. Since 1930, nematodes damaging crops have attracted attention, and it became necessary to spray nematocides. Especially in recent years, in the intensive cultivation of vegetables, corn plants, seedlings, etc., crops and single crop cultivation have been emphasizing the spread of nematode by infecting soil with nematodes for many years.

Organophosphates such as parathion and methacystox are effective only for nematodes that are parasitic on the ground of crops such as rice and planting nematodes. In the root-knot nematode, root rot and nematode nematode, · Soil fumigants such as methyl bromide are effective but their use is restricted due to their strong toxicity. Other nematicides are di-diester, dazometh, cambate, etop, tabbo, primi, and so on.

Rodenticide is a drug used to control rats, moles and other rodents that cause injury to the forestry industry. It is also called rat poison. In Korea, it is treated as a health medicine without being treated as an agricultural chemical. Salicide can be classified as acute and chronic depending on its poisoning, and acute is mainly used.

Examples of acute toxic effects include abiotic agents, barium agents, organic fluoride agents, and zinc phosphates, and those that exhibit chronic toxicity include coumarin-based salfurants such as Warfarin and Tomorin ). Drugs that exhibit acute toxic effects are those that are both short-lived and long-lasting, while pratol is a short-acting, and the yellow phosphorus is a long-lasting fungicide.

To be used as an agricultural chemical, the following conditions must be met. ① It should have a big effect as a small amount. ② There should be no harm to crops. ③ The toxicity to human · livestock should be low. ④ There should be few side effects on agricultural ecosystems. ⑤ Pesticide value and spraying cost should be cheap.

The pesticide is made up of only a small amount of pure active ingredient and the active ingredient of the pesticide and the adjuvant are mixed so as to maintain the biological effect of the pesticide most appropriately. The auxiliary agent is divided into an expanding agent and a spreading agent. The pesticidal composition may further comprise the following auxiliary components.

Diluent [增量 一, diluent]

As a material used to increase the dilution of the main agent or to improve the medicinal effect of the main agent among the formulations of the pesticides, diatomaceous earth, kaolinite, talc, bentonite, .

Spreader [spreader]

It is a substance that improves the physical properties of spray solution by adding emulsifier, hydrating agent and liquid agent in pesticides. The action is spread uniformly on the surface of crops and pests that are sprayed with liquid (Permeability) that permeates the drug into the tissue of the crop by adding permeability to the spraying solution, and to improve the properties (permeability) of the drug. There are soap, casein lime, soapless soap, and non-surfactant (surfactant).

The pesticidal composition of the present invention is removed in a usual manner from vegetables or fruits. In the simplest way, it is washed with flowing water and removed from vegetables and fruits. Recently used pesticides are washed well in water and spontaneously decomposed in the sunlight. Domestic fruits and vegetables are hand rubbed well and there is no big problem if you wash them thoroughly in running water and water. Depending on the type of fruit or vegetables, it can be removed by immersing in water for about 1 to 5 minutes and then washing it in running water.

Or may be washed with brine or vinegar water. For example, after soaking in brine for 20 minutes, washing in flowing water, rinse with weak vinegar or dipping in natural vinegar for 20 minutes, and then rinsing in running water, harmful harmful substances such as pesticides can be removed. The wax residue remaining in the fruit peel can be removed by wiping with a little bit of soju.

Imported fruit such as lemons and oranges can remove wax on the surface, but it is difficult to remove with salt or vinegar alone. Fruits that use the outer surface of the skin, such as lemons, can not avoid pesticide consumption. However, nowadays, a detergent for washing fruits and vegetables is sold separately for such cases, and a detergent can be made directly by mixing grapefruit seed extract, shochu, vinegar, and the like into rice flour fermentation broth.

If the liquid pesticide added with the pigment is sprayed on the vegetables, grains and fruit that we eat, it will be bad for the appearance, but if you wash the vegetables, grains and fruits with the pigment added pesticide cleanly, It is a safe food. In addition, restaurants that use vegetables such as vegetables, grains, and fruits cultivated with pesticides containing these pigments have the advantage of being able to eat vegetables, fruits, and grains in the restaurant without worrying about washing them more thoroughly for customers. In addition, companies or farmers who grow vegetables, grains, fruits, etc., will be able to earn additional profits from cleaning if they are cleaned and sold with the addition of pigmented pesticides. In households, restaurants and businesses that use them, It has the advantage of reducing the time and labor required for washing. It is a liquid pesticide added with pigment, and it has an advantage that it can be easily distinguished from organic agricultural products when it is sprayed on vegetables, grains and fruits.

The pesticidal composition of the present invention is prepared by dissolving the pesticide and pigment of the powder in water.

The pesticide used in one embodiment of the present invention is an insecticide (trade name: Conidos) made by Dongbu Palm Hanon Co., Ltd. It is used at a dilution ratio of 2,000 times, so that the ratio of water to pesticide is 2,000: 1, 1. As shown in Fig. 1, the diluted pesticide was colorless. 1: 1, 1: 3, 1: 4, 1: 5, 1: 7.5, 1, 2, 3, 4, 5 and 6 were mixed with the pesticide powder prepared in the above manner in a weight ratio of agricultural edible pigment (Miryang agar, : 10, and so on. The higher the weight ratio of the black natural food coloring, the more pesticide color is evident.

Vegetables to be sprayed with pesticide added with pigment were tested with cabbage and sesame leaves.

Spraying was carried out as in FIGS. 1 to 3 to spray the pesticide added with the pigment, and the number of times of spraying was 5 times, 10 times, 15 times, 20 times. In the case of sesame leaves, the green color of the sesame leaves was darkened and sprayed 20 times with the concentration of the pigment at 1: 5, but the color of the pigment was not distinguishable (Fig. 4).

In the case of cabbage, it was possible to confirm that the marking in which the pigment is buried in the cabbage even in the case of addition of the low pigment (FIGS. 5 and 6). As the number of spray increases and the concentration of pigment increases, it is confirmed that pigment appears clearly in vegetable.

In order to investigate the effect of the spraying of the pesticide added with the pigment on the vegetables, the experiment was carried out by using the washing time as a parameter of the cabbage and Chinese cabbage sprayed 20 times at a concentration of 1:10. , 10 seconds, 20 seconds, 30 seconds, 40 seconds, and 50 seconds.

As the washing time gets longer, the pigment on the cabbage surface is washed well. (Fig. 7 and Fig. 8). When the pesticide with pigment is used, the degree of washing of the pesticide which can not be visually recognized as in the above drawing can be easily visually distinguished.

Also, after spraying the same with the pesticidal composition of the present invention on cabbage and cabbage, all of them were washed every 20 seconds, but in the case of Chinese cabbage, washing was much less than cabbage because of wrinkles on the surface. (FIGS. 9, 10, and 11). It can be seen that the surface conditions of the vegetables, fruits, and grains to be cleaned are different from each other in order to remove pesticides. You can visually confirm that the vegetables, fruits, and grains are safe to eat. Vegetables have a cursory layer, so pigments do not enter the plant well, but the cut part shows a little flaky. (Fig. 7 and Fig. 8). If the mites are transferred, the pesticide will be diffused therein. Therefore, washing or removing the contaminated parts completely will reduce the damage of pesticides.

The pesticidal composition of the present invention can confirm whether the pesticide added with the pigment is washed well when the fruit or vegetable is wiped by confirming that the pesticide is on the naked eye of a human being, and the pesticide- So as to minimize the damage caused by pesticides to humans and livestock.
