Description

Eco-friendly organic materials for soil pest control {ENVIRONMENT-FRIENDLY ORGANIC AGRICULTURAL PRODUCTS FOR SOIL INSECT PEST CONTROL}

The present invention relates to an environmentally friendly organic material for soil pest control and a method of manufacturing the same. More specifically, the present invention relates to environmentally friendly organic materials effective for controlling soil pests, in particular soil nematodes, and methods for producing the same.

Azadilactin, the main component of Neem fruit oil, has a pesticidal effect on various pests, and is mainly produced in Southeast Asia, including India. In Korea, the pesticidal effect of azadilactin has been known for more than 10 years, and has been tested on several pests. However, since nim oil has a variety of quality, such as the content of the pesticide components by production site, it is difficult to commercialize the product because it cannot guarantee the effect stably.

 In the present invention, not only enjoy the effect of supplying organic matter to the crops with the main ingredients of squeezed (nymbak) and tobacco powder left after squeezing the oil of the fruit of the Neem fruit, but also to control soil pests, in particular soil nematodes, more particularly root-knot nematodes To provide.

So far, melons, watermelons, ginseng, tomatoes, carrots, cabbages, peppers, and peanuts have been severely damaged by soil nematodes, especially root-knot nematodes, but they have no choice but to rely on pesticides because they do not have eco-friendly materials to control them.

In recent years, organic pesticides have been spreading widely, and greenhouse house cultivation has become more common, and pesticides are being avoided. In particular, farmers working in plastic houses (melon, melon watermelon, red pepper, tomato, etc.) are a major cause of damage due to the damage of root-knot nematodes. We are looking forward to the development of soil pest control agents.

In the present invention, in addition to the control effect of using organic materials and eco-friendly materials, the tobacco powder that is discarded as waste is used, so that the cost effect of resource recycling can be expected.

Tobacco powder is crumbs and leaf veins produced when processing raw tobacco ingredients. In the present invention, the tobacco powder is used together with the nim oil, and since these two raw materials are rich in organic matter, the fertilizer effect and the soil improvement effect can be expected from this.

In addition, chitin and photosynthetic bacteria, which are other components of eco-friendly organic materials according to the present invention, become a nutrient source of actinomycetes and promote the reproduction to inhibit the growth of pathogens such as fusarium, lysatonia, etc. The disease caused by can be significantly reduced.

These days, crops grown repeatedly in the same plastic house, which are fixed facilities, or grown for a long period of time, such as ginseng, for 4 to 6 years, suffer severe soil nematode damage. In addition, since vinyl mulching is cultivated to suppress weed generation, it is difficult to apply fertilizer. Therefore, it is necessary to give organic fertilizers with a long-lasting fertilizer effect. therefore. It was urgent to develop agricultural materials that could achieve both effects, such as soil pest control and organic fertilizer. Therefore, the present inventors will solve the following problems in consideration of the demand and environmental aspects of the farm.

지 Research eco-friendly organic farming methods by using natural products to control soil nematodes, which are heating pests, without using pesticides and chemical fertilizers.

증대 Increase the organic matter content, which is essential for eco-friendly organic farming, so that the fertilizer's effects can be sustained for a long time without the use of chemical fertilizers.

을 Promotes the reproduction of actinomycetes, inhibits the growth of pathogens, filamentous fungi, and significantly reduces soil diseases.

기 You can enjoy the labor saving effect by controlling soil pests such as root-knot nematodes, garlic, and onion capillary flies at the same time, as well as airing the soil before planting.

As a result of intensive research to solve the above problems, the inventors have succeeded in developing an organic material that can environmentally control soil nematodes, which are heating pests, by using environmentally friendly natural products with excellent insecticidal properties. The organic material according to the present invention can play a role as a fertilizer because of its high organic content, so that it is possible to control the environmental nematode in the form of organic fertilizers without pesticides, which is a soil nematode that can be eliminated with conventional pesticides. This is a major step forward in light of recent farming and consumer demand for eco-friendly organic farming.

The organic material according to the present invention may be made into a simple granular formulation that is easy to use or may be provided as a compost with an increased moisture content.

Hereinafter, the eco-friendly organic materials of the present invention will be described in more detail.

Eco-friendly organic materials for soil pest control of the present invention contains 40 to 500 ppm (0.004 to 0.05%) of azadilactin and 1 to 30% by weight of tobacco leaf as an effective pesticidal ingredient, in addition to 35 to 90% by weight of organic matter and soil diseases It contains 2 to 35% by weight of the control component. Preferably it contains 40 to 100 ppm (0.004 to 0.01%) of azadilactin, 5 to 25% by weight of tobacco leaf, 50 to 70% by weight of organic matter, and 5 to 30% by weight of soil pest control component. At this time, more than 40 ppm of azadilactin, tobacco powder, that is, nicotine added through the leaf tobacco powder should be added in an amount of at least 15 ppm or more to increase the synergistic effect and the insecticidal effect against soil pests including soil nematodes.

Azadirachtin (Azadirachtin), which is an insecticidal component of mulberry tree used as an insecticidal component in the present invention, is contained in trees, leaves, fruits, and the like, among which the most is contained in the fruit. Azadilactin in the fruit is obtained along with the oil, which is called neem oil. Most of the residue left after extracting Nim Oil is composed of organic matter, which also contains a small amount of azadilactin. Nimbak can be used as an insecticide in itself in the present invention, and can also be used as an oily vegetable vegetable oil extender. If the content of azadilactin in the nimbak is too small, the azadilactin must be added to increase the main component content.

Tobacco powder, which is another insecticidal ingredient of the present invention, that is, nicotine component of the leaf tobacco powder was also found to have a pesticidal effect on soil nematode, and then mixed with azadilactin component was developed as an organic fertilizer and soil nematode control agent.

The eco-friendly organic material of the present invention contains an extender in addition to the pesticidal ingredient mainly containing azadilactin and nicotine. As the extender, vegetable or animal organic substances are largely used.

Organic ingredients are ingredients added to use the eco-friendly organic materials of the present invention as a fertilizer, so as to increase the content of organic matter, soybean meal, castor meal, rapeseed oil meal, rice bran oil, nymph meal, various oils such as sawdust, molasses, palm bark, Various vegetable organics such as peat and compost and animal organic matters such as fishmeal, fishmeal, blood bone, powdered leather powder, dragonfly, chitosan, chitin calcium, amino acid, guano, livestock manure, etc. can be added alone or as a extender. Can be.

In addition, the eco-friendly organic materials of the present invention contains chitin, chitosan or photosynthetic bacteria as soil pest control components, which become a nutrient source of actinomycetes and promote the reproduction of actinomycetes and inhibit the growth of filamentous fungi such as fusarium and lysatonia. It plays a role. Long-term use of these components can significantly reduce the disease caused by soil pathogens. Photosynthetic bacteria may be commercially available or directly cultured. As a photosynthetic bacterium of the present invention used in the following examples, red staphylococcus bacterium, which was entrusted to the Taewon Agricultural Research Institute, was used to culture the spawn in a 200 L incubator.

Eco-friendly organic materials of the present invention can be provided as a granular formulation, ie granules and compost.

In the composting process, compost is secondary fermented (after ripening) to dry the water to about 30%, and chitin and other tobacco powder are mixed with chitin and calcium powder, and the azadilactin solution and the photosynthetic bacterial culture are sprayed and mixed. Adjust it to 35-45% to allow photosynthetic bacteria to live well and function.

Granular formulations, on the other hand, are prepared by optionally further comprising a granulating agent, a dispersant, and a binder component in addition to the pesticide component, organic substance, and soil pest control component.

At least one mineral component selected from dolomite, limestone, lime silicate, zeolite, diatomaceous earth, kaolin, leadstone and bentonite is used for granulation. These granulating agents are used in an amount of 5 to 50% by weight, and by using these granulating agents, when granulating organic materials into granular form, it is convenient to use and soil improving effect. The particle size of the granules is in the range of 1 to 15 mm, preferably 2 to 5 mm. If the particle size is too large, soil moisture alone is difficult to disperse, and if too small, it is difficult to work such as blowing in the wind.

As a dispersant, materials widely used in this field such as (calcium ligno sulfate) or sodium ligno sulfate (SLS) may be used. The amount used is 1 to 20% by weight, preferably 1 to 10% by weight, depending on the moisture content.

There are many types of binders, but those contained in the present invention are preferably made of natural products. Condensed molasses soluble (CMS) is a concentrated molasses and is used as a binder in the present invention. In addition, sugars, starches, dextrins, cyclodextrins, lignin and the like can be used. The binder is used in an amount of 1 to 10% by weight, preferably 3 to 5% by weight.

 The following examples and test examples are intended to explain the contents of the present invention in more detail, and the scope of the present invention is not limited by these examples.

 Nematodes, which are the most heating soil pests, and root-knot nematodes are most severe in green house cultivation, crop cultivation, and perennial crop cultivation. These nematodes are difficult to control even with pesticides that have recently been registered as soil nematode control agents, and farmers producing eco-friendly organic products have no control measures. According to the present invention, since the environmentally friendly root-knot nematode control agent manufactured using natural materials is not a pesticide, it can effectively fertilize soil pests such as root-knot nematodes and fertilize the crops, when used in crops, Both farmers and consumers can produce true eco-friendly organic produce that can be eaten with confidence.
