Description
Technical Field
The invention relates to the field of plant sterilization, and in particular relates to a pesticide composition.
Background
Chitosan, also called chitin, crab chitin, etc., is widely present in the shells of lower animals, such as arthropods of crustacea, entomophytes and arachnids, and the cell walls of lower plants, such as fungi, algae, yeast, etc., and is one of the most abundant natural high molecular compounds and the second most nitrogen-containing compound in nature, and the annual biosynthesis amount of the chitosan can be estimated to be as much as 100 hundred million tons. The chitosan has the advantages of being used as a natural polymer, has good safety, biodegradability, biocompatibility, unique physicochemical property and biological activity, and has become a hotspot in pesticide research in recent years by utilizing and researching chitin for hundreds of years, particularly in recent years under the background of sustainable agriculture and production of harmless agricultural products.
The chitosan can inhibit the growth of pathogenic matter and raise the disease resistance and immunity of crop through altering the structure and function of pathogenic matter cell membrane. The chitosan can effectively prevent and control crop diseases such as cucumber downy mildew, powdery mildew, tomato late blight, virus diseases, apple anthracnose, rice blast and the like, and has a wide bactericidal spectrum.
Because people depend on using a single type of bactericide for a long time, pathogenic bacteria are easy to generate drug resistance, so that the chemical dosage of the bactericide is increased sharply, the economic burden of farmers is increased, and the environment is polluted.
Accordingly, the present invention is directed to a method of making a semiconductor device.
Disclosure of Invention
The invention aims to provide a pesticide composition, which solves the technical problem that a single type of bactericide in the prior art has poor sterilizing effect.
In order to solve the problems, the invention adopts the following technical scheme:
a pesticide composition comprises the following components in parts by weight:
4% -30% of valienamine;
0.5% -14% of chitosan;
the balance of auxiliary agents.
Valienamine, which is called Valifenaflate in English and is called N- (isopropoxycarbonyl) -L-valyl- (3RS) -3- (4-chlorphenyl) -R-alanine methyl ester in chemical name, belongs to amino acid derivatives, has strong systemic activity, has high biological activity on plant diseases caused by oomycetes, and plays roles of protection, treatment and eradication on the surface and in the body of the plant.
The method for preparing the pesticide preparation by combining the effective components of different pesticides is a quick and effective method for developing and researching new pesticides at present. The mixing of different types of pesticidal active ingredients generally shows three types of action: additive action, synergistic action and antagonistic action.
However, after different types of pesticide active ingredients are mixed, the specific action is unpredictable; the pesticide active ingredients are not simply mixed, and auxiliary ingredients of the pesticide preparation are required to be added, the type and the dosage of the auxiliary ingredients of the pesticide preparation directly influence the exertion of the pesticide active ingredients, and the relationship between the dosage and the pesticide effect is not linear.
According to the pesticide composition provided by the invention, after the valienamine and the chitosan are compounded, late blight can be effectively prevented and treated, the prevention and treatment effect is superior to that of a single agent, and the lasting period is long. The control effect of the plant reaches over 79.8 percent in 14 days after the last application of the plant, and the plant has no phytotoxicity to target crops in the application range of the test. After the valienamine and the chitosan are compounded according to different proportions, the use amount of effective components is greatly reduced under the condition of the same control effect, thereby reducing the harm to the environment and delaying the resistance of pests.
Preferably, the auxiliary agent comprises an auxiliary agent and a filler, wherein the auxiliary agent accounts for 10-20% of the total weight of the composite material. Different auxiliaries and/or fillers are selected from different pesticide formulations.

The influence of the filler on the pesticide effect is smaller than the influence of the auxiliary agent on the pesticide effect, so that the limitation of the content of the auxiliary agent is beneficial to improving the pesticide effect.
