Description

Technical Field

[0001] The present invention relates to the field of pesticide research and development, and particularly to a soluble binary compound pesticide for piercing-sucking mouthpart pests and its application in controlling piercing-sucking mouthpart pests. Background Art

[0002] In the process of agricultural production, applying chemical agents is the most effective means to control plant diseases and pests. However, there are problems such as the easy generation of pest resistance, and the long-term continuous high-dose application of a single chemical binary compound pesticide is likely to cause single cumulative residue of the pesticide, resulting in environmental pollution. Rational compounding or mixing of chemical agents has positive characteristics such as expanding the insecticidal spectrum, improving the control effect, extending the application period, reducing the dosage of pesticides, reducing phytotoxicity, reducing residues, and delaying the occurrence and development of pest drug resistance and resistance. Based on indoor screening and field trials, we screened the compounding of nitenpyram and flonicamid, which has an obvious synergistic effect. The patent application No. 201310525403.3 protects the scope of emulsifiable concentrates, suspensions, wettable powders, water dispersible granules, emulsions, microemulsions, granules, and microcapsules. Currently, there is no report on the soluble solution of the compound of nitenpyram and flonicamid. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a soluble binary compound pesticide for piercing-sucking mouthpart pests, which is used to control and kill piercing-sucking mouthpart pests. The active ingredients nitenpyram and flonicamid are selected for binary compounding. After compounding, it can delay the process of drug resistance, reduce the dosage of pesticides, lower the use cost, reduce environmental pollution, expand the insecticidal spectrum, and has a synergistic effect of compound addition.

[0004] To achieve the above object, the technical solution adopted by the present invention is: a soluble binary compound pesticide for piercing-sucking mouthpart pests, the pesticide is a soluble liquid agent, and the components of the pesticide include nitenpyram, flonicamid and an adjuvant. The mass ratio range of nitenpyram and flonicamid in the pesticide is 1:50 to 50:1.

[0005] Further, the adjuvant includes cyclohexanone, methanol and a wetting agent.

[0006] Further, the wetting agent is emulsifier 600# or block polyether emulsifier or castor oil polyether emulsifier.

[0007] Further, the total mass fraction of nitenpyram and flonicamid in the pesticide is 1% to 80%.

[0008] Further, the total mass fraction of nitenpyram and flonicamid in the pesticide is 5% to 50%.

[0009] The present invention also provides an application of a pesticide: for controlling piercing-sucking mouthpart pests.

[0010] The beneficial effects of adopting the above technical solutions are as follows:

[0011] 1. The insecticidal spectrum is broadened, and the quick-acting property and long-lasting property are effectively complementary. After nitenpyram and flonicamid are compounded, they complement each other's advantages, have good control effects on piercing-sucking mouthpart pests, etc., and both the quick-acting property and the long-lasting property are excellent.

[0012] 2. The control effect is enhanced. After nitenpyram and flonicamid are compounded, the interaction type is additive and there is a synergistic effect, the control effect is enhanced, and it is better than the single use effect.

[0013] 3. It avoids the rapid occurrence of pest resistance caused by the use of a single pesticide for control, and delays the occurrence of pest resistance.

[0014] 4. The amount of pesticide used is reduced, the use cost is lowered, and environmental pollution is alleviated. Specific embodiments

[0015] The soluble binary compound pesticide for piercing-sucking mouthpart pests of the present invention, the pesticide is a soluble liquid formulation, and the components of the pesticide include nitenpyram, flonicamid and an adjuvant. The mass ratio range of nitenpyram and flonicamid in the pesticide is 1:2.8.

[0016] The adjuvant includes cyclohexanone, methanol and a wetting agent.

[0017] The wetting agent is emulsifier 600#.

[0018] The total mass fraction of nitenpyram and flonicamid in the pesticide is 10%.

[0019] The pesticide of the present invention is used for controlling piercing-sucking mouthpart pests.

[0020] The compound binary compound pesticide is used for controlling piercing-sucking mouthpart pests, such as aphids, thrips, whiteflies, leafhoppers, and pear psyllids.

[0021] The preparation method of the compound binary compound pesticide of the present invention is as follows: Add a specified amount of cyclohexanone and methanol into a metering tank respectively, put them into a preparation kettle, and add a metered wetting agent, nitenpyram technical, and flonicamid technical under stirring at room temperature, and continue to stir until the technicals are completely dissolved. Take samples for detection of indexes such as content, solubility, and emulsification. After passing the inspection, filter them into a transfer tank for sub-packaging.

[0022] The above description is only proposed as a feasible technical solution of the present invention, and does not serve as a single limiting condition for its technical solution itself.
