Description
Technical Field
The invention belongs to the technical field of pesticides, and relates to a compound medicament composition for preventing and treating bemisia tabaci and aphis cucurbitae, in particular to a compound medicament composition of dicyclopropyl and thiacloprid.
Background
Bemisia tabaci (Bemis tabaci) and Aphis cucurbitae (Aphisgosyphilis) are important pests of crops, and the two pests usually occur on the crops simultaneously and are harmed together.
Bemisia tabaci belongs to the class Hemiptera and the family Bemisia and is an important pest of crops. The pest has wide host range, and can damage vegetables, cotton, tobacco, etc. Bemisia tabaci is mainly harmful to the back of host leaves, plant juice is absorbed by thorns, plants are weak, nymphs and adults can also secrete honeydew to induce the generation of sooty mould, and when the density is high, leaves are black, so that photosynthesis is seriously influenced; in addition to direct damage, the pest also transmits a variety of viral diseases, which severely affect the yield and quality of host plants. The bemisia tabaci has the characteristics of high diffusion speed, high reproduction rate, high resistance increase and the like, and is difficult to be effectively prevented and treated by common chemical agents.
Guarazu aphid belongs to the family of hemiptera and Aphidae. The pests suck juice on the back sides, young tips and young stems of the leaves of the crops by adult aphids and several aphids, so that the leaves of the crops are curled, yellow spots or withered and withered, and even the growth of the crops is stopped; honeydew is discharged when the aphids are harmful, the photosynthesis of crop leaves is seriously influenced, and sooty mould is caused; meanwhile, the pests are also virus vectors of various virus diseases, and the yield and the quality of crops are seriously influenced. The aphid has the characteristics of short development period, high reproductive capacity, fast drug resistance increase and the like, and is difficult to control.
The existing agents for preventing and controlling bemisia tabaci mainly comprise thiamethoxam, clothianidin, lambda-cyhalothrin and other compound agents, and the agents for preventing and controlling melon aphid mainly comprise thiamethoxam, imidacloprid, acetamiprid, lambda-cyhalothrin and other compound agents, but the prevention and control effects on two pests are not ideal. The drug is used scientifically for a long time, so that the resistance of bemisia tabaci and aphis cucumeria is enhanced, and the harm of the bemisia tabaci and aphis cucumeria cucumerina cannot be effectively controlled despite the continuous increase of the dosage.
Dicentrazone, commonly known as Afidopyropen in english, is found in biofermentation products and is a propylene compound. The chemical name is [ (3S,4R,4aR,6S,6aS,12R,12aS,12bS) -3- (cyclopropylcarbonyloxy) -1,3,4,4a,5,6,6a,12,12a,12 b-decahydro-6, 12-dihydroxy-4, 6a,12 b-trimethyl-11-oxa-9- (3-pyridyl) -2H, 11H-benzo [ f ] pyran [4,3-b ] chroman-4-yl ] cyclopropanecarboxylic acid methyl ester', the structural formula is aS follows:
thiacloprid, commonly known by the english name Thiacloprid, is a neonicotinoid insecticide. The chemical name is "(3- ((6-chloro-3-pyridyl) methyl) -1, 3-thiazoline-2-ylidene) cyanamide". The structural formula is as follows:
at present, the compound of the diproprionate and thiacloprid for preventing and controlling bemisia tabaci and melon aphid is not reported.
Disclosure of Invention
In order to solve the problems, the applicant finds that the compound of the diproprionate and the thiacloprid according to a specific proportion shows a remarkable synergistic effect on the basis of intensive research, and the obtained novel medicament composition has a good control effect on agricultural pests such as bemisia tabaci, melon aphid and the like.
The invention relates to a compound medicament composition for preventing and treating bemisia tabaci and aphis cucumeria, which comprises the following raw materials in percentage by weight: 24.0 percent of the total of the diproprionate and the thiacloprid, 7.0 to 13.0 percent of the auxiliary agent and 69.0 to 63.0 percent of the filler carrier.
In the invention, the insecticidal mechanism of the dicyclopropionate is as follows: the modulator interferes the function of the string organ vanilloid receptor subfamily channel of pests, so that the pests lose the induction on gravity, balance, sound, position, motion and the like, and the pests are deaf, lack coordination and direction feeling, cannot eat, lose water and finally die due to hunger. The pesticide has the characteristics of quick response, high efficiency, broad spectrum and the like, has excellent leaf penetration capability, can effectively control various pests such as hemiptera pests (whitefly, aphid and the like), and particularly has excellent control effect on pests with resistance to nicotine, organophosphorus, pyrethrins and pymetrozine.
In the invention, the insecticidal mechanism of the thiacloprid is as follows: mainly acts on insect nerve postjunctional membranes, and is combined with a nicotine acetylcholine receptor to interfere normal conduction of insect nervous systems, so that the blockage of nerve channels is caused, and a large amount of acetylcholine is accumulated, so that the insects are excited abnormally, and are killed by general spasm and paralysis. The pesticide has strong contact poisoning, stomach poisoning and systemic effects, and has good control effect on various pests such as Hemiptera (whitefly, aphid, etc.), Lepidoptera (cotton bollworm, beet armyworm, etc.). The drug resistance monitoring shows that when the pesticide is used alone, pests are easy to generate drug resistance, so that the cost performance of controlling intractable pests is obviously reduced.
In the invention, when the two substances are combined, due to different insecticidal mechanisms of the dicyclopropyl and the thiacloprid, the compound composition of the two agents can simultaneously act on different sites of a target, so that the advantages are complemented, and the control effect on bemisia tabaci and aphis cucumeria is effectively improved.
The auxiliary agent is a compound agricultural auxiliary agent and is a mixture of 2-naphthalene sulfonic acid formaldehyde polymer sodium salt (96% in Wuhan, a product of Co-creation science and technology Co., Ltd.), sodium dodecyl sulfate (98% in Ornkian synthetic chemistry Co., Ltd.) and nekal (98% in Zhengzhou Chengnio chemical products Co., Ltd.). The sodium salt of the 2-naphthalenesulfonic acid formaldehyde polymer plays a role of a dispersing agent, the lauryl sodium sulfate plays a role of wetting and permeating, the absorption of the effective components of the composition by the bemisia tabaci, the aphis cucurbitae and the crops is facilitated, the surface tension of water can be obviously reduced by pulling the starch open, the penetration force and the wetting performance are excellent, the rewettability is also excellent, and the emulsifying, diffusing and foaming performances are realized. The sodium salt of the 2-naphthalenesulfonic acid formaldehyde polymer, the sodium dodecyl sulfate and the nekal can be scientifically compounded and used, can effectively play roles in dispersing, wetting, permeating and suspending, and is beneficial to the absorption of the effective components of the composition by bemisia tabaci, the aphis cucurbitae and the crops. The higher the absorption rate of the effective components of the composition by the bemisia tabaci and the aphis cucumeria, the better the killing effect on the bemisia tabaci and the aphis cucumeria; the higher the absorption rate of the effective components of the composition by crops is, the higher the killing effect of bemisia tabaci and aphis cucumeria during the process of piercing the cells of the crops to suck the juice is. The auxiliary agent improves the control effect of the composition on target pests, can effectively control bemisia tabaci and aphis cucumeria, realizes the pesticide reduction control on the pests, protects the ecological environment, reduces the pesticide residue of crop products, and ensures the safe production of crops, thereby having important significance. The raw materials added by the aid are all converted into products, the yield is high, three wastes are not generated, and the control effect on bemisia tabaci and melon aphids is effectively improved. The optimal proportion of the auxiliary agent is as follows: the sodium salt of the 2-naphthalenesulfonic acid formaldehyde polymer accounts for 5.8% of the total weight of the pesticide, the sodium dodecyl sulfate accounts for 2.4% of the total weight of the pesticide, and the nekal accounts for 1.8% of the total weight of the pesticide.
