Problems solved by technology

[0014] The several chitin synthesis inhibitor compounds mentioned above have relatively high insecticidal selectivity, narrow insecticidal spectrum, unsatisfactory quick-acting properties and short duration of action.
And after a long period of continuous use, pests are prone to develop drug resistance, resulting in a relatively large amount of use in agricultural production, relatively high use costs, and also increased environmental pollution.
In order to solve the problems encountered above, improve the quick-acting and long-lasting effects of drugs, and reduce the cost of using pesticides, we screened out spinosad and Chitin synthesis inhibitor compound is a two-component composition agent. Spinetoram is a biological pesticide, which is highly efficient and environmentally friendly. It has obvious synergistic effect when compounded with chitin compounds, and so far no Find related reports about the combination of the two

Embodiment 2

[0045] Embodiment 2: the processing and embodiment of spinosad and diafenthiuron aqueous emulsion

[0046] Spinosad 4g, diafenthiuron 14g, polyoxyethylene fatty alcohol ether 6g, dichloromethane 7g, sodium citrate 3g, ethylene glycol 4g, silicone oil 1g, xanthan gum 7g, water to make up to 100g. Add the original drug spinosad and diafenthiuron, solvent, emulsifier, and co-solvent together to dissolve into a uniform oil phase; mix part of water, antifreeze, antimicrobial and other pesticide adjuvants Together to form a uniform water phase; while stirring at high speed in the reactor, add the oil phase to the water phase, slowly add water until the phase inversion point is reached, turn on the shearing machine for high-speed shearing, and add the remaining water, shear about After half an hour, an oil-in-water emulsion is formed. That is, the aqueous emulsion of the insecticidal composition containing spinosyn and diafenthiuron was prepared.

Abstract

The invention relates to a spinetoram compounded insecticidal composition and belongs to the field of pesticide compounding. Active components of the spinetoram compounded insecticidal composition comprise spinetoram and chitin synthesis inhibitor compounds. A weight percentage of the spinetoram to the chitin synthesis inhibitor compounds is (1 to 90): (90 to 1), and preferably, the weight percentage is (1 to 45): (60 to 3). The spinetoram compounded insecticidal composition comprises 1 to 90% by mass of the active components, and preferably, comprises 3 to 7% by mass of the active components and the balance auxiliary ingredients which can be used in pesticides and are acceptable. The spinetoram compounded insecticidal composition can be processed into emulsion in water, microemulsion, missible oil, a suspending agent, wettable powder and water dispersible granules by known methods. The spinetoram compounded insecticidal composition has the advantage that through the active components of spinetoram and the chitin synthesis inhibitor compounds, control of lepidopterous, thysanopterous and homopterous pests such as cnaphalocrocis medinalis guenee, diamondback moth, prodenia litura, cotton bollworm, beet armyworm and thrip is realized.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition which uses spinosad and chitin synthesis inhibitor compounds as active ingredients for dual compounding. Background technique [0002] Spinetoram, Spinetoram (XDE-175) is a novel spinosyn insecticide developed by Dow AgroSciences, and it is the second generation product of spinosyn. He has solved the problem that spinosad has good insecticidal effect on vegetable crops, but the pest control of fruits and nuts is not ideal, especially for pome fruit borer apple leaf tortrix which cannot be controlled by spinosad. , and its insecticidal spectrum is wider than that of spinosad. In addition, it has the advantages of less impact on main beneficial insects, lower dosage per unit area, and short residual period in the environment. It won the 2008 "US President's Green Chemical Challenge Award". Its composition structural formula is: [0003] ...
