Description

Plant protection oil composition and preparation method thereof, microemulsion, spreading agent and pesticide

The present invention relates to a plant protection oil composition and a preparation method thereof, a microemulsion, a spreader, and a pesticide, and more particularly to a plant protection oil composition comprising water and oil having a nanometer-sized bubble.

In recent years, bio-pesticide has provided another safe, economical and effective choice. It is far less dangerous than traditional chemical agents, has higher specificity, and is harmless to natural enemies of humans, animals, wild animals, pests and beneficial insects. Furthermore, the use of small amounts of biological pesticides is effective, rapid decomposition, low exposure risk, no pollution problems, no residual amount, so there is no need to set a safe harvest date, and it can be harvested immediately after application.

According to the definition of the US Environmental Protection Agency, biological pesticides are significantly different from traditional chemical agents because biological pesticides have a non-toxic mechanism of action, target specificity, and can be produced by organisms in the environment. Classification by source includes: (1) microbial pesticides, including bacteria, fungi, algae, protozoa or viruses. Its mechanism of action can be through the production of toxins (such as Bacillus thuringiensis), invasive parasites (such as Beauveria, Beauveria), pathogenicity (such as baculovirus) and competition (such as the cross-protection of viruses for plants). (B), biochemical pesticide (biochemical pesticide), there are four distinct biological function categories (1) chemical carrier (2) hormone (3) natural plant regulator (4) enzyme. (3) Plant-produced pesticides, including substances introduced into plants, for the purpose of being used as pesticide users. Bacillus thuringiensis is a kind of microbial pesticide preparation, and the transgenic crop containing the Suri insecticidal insecticidal gene is also a pesticide produced by plants. However, depending on the subject to be administered, it can be classified into a bioinsecticide, a biofungicide, and a bioherbicide. Because microbial preparations are safe and non-toxic to natural enemies, humans, animals and plants, they do not pollute air, water and soil, have the characteristics and advantages of protecting environmental quality, have low development costs, and are not resistant to pests and diseases. Some pest pathogens Microorganisms and viruses and certain bacteria (emulsified bacteria) still have long-term insect-preventing effects. They are a non-pesticide prevention and control technology that is worthy of attention. However, microbial control cannot completely replace other prevention and control. Microbial control alone has its shortcomings. Therefore, other measures such as chemical control should not be mutually exclusive, but must be closely coordinated with each other, complement each other and complement each other, and play a proper coordination role in the integrated pest control system.

In general, in the prevention and control of agricultural crop pests and diseases, relying on chemical synthesis of pesticides, although chemical pesticides have a very good pest control effect, but chemical pesticides are easy to destroy the ecological balance, and if the human body eats the residual chemical pesticides, the fruits and vegetables will harm the human body. health.

In contrast, biological pesticides refer to non-chemical synthesis, derived from natural substances or living organisms, have good biocompatibility, are safe for human and animal organisms, and are less polluting to the environment, Sex pesticides can be divided into two major categories: plant pesticides and microbial pesticides.

A plant-based pesticide is a plant-specific part that inhibits the growth of plant pathogens and pests, or extracts the active ingredient of the specific part. For example, the toxin is isolated from the seeds of white peas. Causes the death of insects and the extraction of water from the beans The substance can inhibit the growth of Rhizoctonia solani which causes yellowing of vegetable plants.

Microbial pesticide refers to a microorganism and a metabolite of microorganisms capable of inhibiting the growth of plant pathogenic bacteria and pests. The microorganism contains bacteria, viruses and fungi, and the metabolite of the microorganism refers to a substance which is produced by the microorganism against another organism.

In the case of plant protection preparations, at present, commonly used such as bitter oil, narrow-field oil, sunflower oil, etc. in the market, in use, the day must be used on the same day, otherwise there will be rancidity, other bacteria, As a result of the deterioration of the quality of the oil, the effect of plant protection will also decline. Furthermore, the degree of emulsification of the conventional oil agent is insufficient, so the suspension in the water is not uniform, the dose sprayed on the surface of the plant is not uniform, and the pores are easily blocked, so that the evapotranspiration cannot be performed, resulting in phytotoxicity.

Therefore, how to propose a plant protection preparation, which can achieve better control effect, longer control period, and no phytotoxicity to crops, is the problem that the industry wants to improve.

Wherein, the plant protection oil composition is a water-in-oil liquid form, the principle thereof It is because the nano-scale bubbles have the characteristics of both hydrophilic and lipophilic, and their negative charges can adsorb oil molecules, and the oil molecules and water molecules can be stably combined. Therefore, the plant protection oil composition proposed by the invention does not need to additionally add an emulsifier, and the plant protection oil composition can be sprayed on the leaf surface more uniformly after being diluted, and the prevention and treatment is more comprehensive, and further, The nano-scale water molecules and the molecules have the property of being able to exist in the liquid for a long period of time, and thus can make the control period longer and more cost-effective. Furthermore, since it can be uniformly sprayed on the surface of the crop, it is avoided that the pores are blocked and the evapotranspiration cannot be caused to cause phytotoxicity.

The present invention further provides a microemulsion comprising at least one of the aforementioned plant protection oil compositions, which can be applied to a leaf or leaf back of a crop by being diluted with water and applied to the crop. The prevention and control of pests and diseases can reduce the phytotoxicity, and the effect period is longer, the use cost is reduced, and the control effect is improved.

And a spreading agent comprising at least one of the aforementioned plant protection oil compositions, which enables use of a fertilizer or a pesticide to uniformly spread the liquid or fertilizer on the leaf surface and increase the foliage The area of contact increases the adhesion, which can extend the effectiveness of pesticides and fertilizers, and reduce the number of uses and costs.

A preparation method of a plant protection oil composition comprising mixing a fat of about 10 to 80% by weight with a water containing a nanometer-sized bubble in a weight percentage of about 15 to 99.9%. Among them, preferably, the fat is a nanometer-grade fat. Preferably, the size of the bubbles and grease is between 1 nm and 100000 nm.

Preferably, the oil is from vegetable oil, olive oil, sunflower oil, soybean oil, peanut oil, rapeseed oil, sesame oil, mustard oil, almond oil, palm oil, crude coconut oil, paraffin oil, mineral oil, linseed oil, palm oil.
