Embodiment 1

[0019] The insecticidal composition described in embodiment 1 is a suspending agent, and the percentages of each component are respectively:

[0020] Active ingredient A1~70%,

[0021] Active ingredient B1~70%,

[0022] Dispersant 5-20%,

[0023] Antifreeze 1~5%,

[0024] Thickener 0.1~2%,

[0025] Defoamer 0.1~0.5%,

[0026] pH adjuster 0.1~5%,

[0027] water balance.

[0028] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A and B, grind in a ball mill for 2 to 3 hours, so that the particle diameter is below 5mm, and then Prepare the suspension formulation of the insecticidal composition of the present invention.

Embodiment 2

[0029] The insecticidal composition described in embodiment 2 is an emulsion in water, and the percentages of each component are respectively:

[0030] Active ingredient A1~70%,

[0031] Active ingredient B1~70%,

[0032] Emulsifier 2~30%,

[0033] Solvent 5~15%,

[0034] Stabilizer 2~15%,

[0035] Antifreeze 2 to 5%,

[0036] Defoamer 0.1~8%,

[0037] Thickener 0.1~2%,

[0038] water balance.

[0039] The specific operation steps are as follows: the active ingredients A and B, a solvent and an emulsifier are mixed together to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reactor, slowly add water until reaching the phase inversion point, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain the insecticidal combination of the present invention water emulsion formul...

Embodiment 3

[0040] The insecticidal composition described in embodiment 3 is a microemulsion, and each component percentage is respectively:

[0041] Active ingredient A1~70%,

[0042] Active ingredient B1~70%,

[0043] Emulsifier 10-30%,

[0044] Antifreeze 1~10%,

[0045] Stabilizer 0.5~10%,

[0046] Solvent and co-solvent 20-45%,

[0047] water balance.

[0048] The specific operation steps are: completely dissolve the active ingredients A and B with a solvent and a co-solvent, then add other adjuvants, mix well, finally add water, and after fully stirring, the microemulsion preparation of the insecticidal composition of the present invention can be obtained .

Abstract

The invention discloses a tolfenpyrad and cartap insecticidal composition. The insecticidal composition comprises a first active ingredient tolfenpyrad and a second active ingredient cartap as well as commonly used auxiliary components, wherein the weight ratio of tolfenpyrad to cartap is (20: 1 )-(1: 10). A large number of indoor and outdoor tests indicate that the insecticidal composition has a synergistic interaction, expands an insecticidal spectrum, and has a good prevention and control effect for pests such as chilo suppressalis walker, scirpophaga incertulas and cnaphalocrocis medinalis on rice, plutella xylostella, beet armyworm, pieris rapae, thrips and aphids on vegetables; and simultaneously, the use amount of pesticides is reduced, residues of the pesticides on crops are lowered, the pollution to the environment is reduced, and the generation of pest resistance to insecticide is delayed.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to a binary compound compounded with tolfenpyrad and cartap as active ingredients, which is mainly used in the prevention and control of various pests on vegetables and rice. Background technique [0002] Tolfenpyrad is a new type of pyrazole heterocyclic insecticide and acaricide. Its main mechanism of action is to prevent the oxidative phosphorylation of insects. The drug has a wide insecticidal spectrum, and has a high control effect on various Pteroptera, Hemiptera, Coleoptera, Thysanoptera, and Diptera pests and mites. It is widely used in vegetables, fruit trees, flowers, and tea. Pest control of other crops. [0003] Cartap is a nereistin insecticide with strong contact, stomach poisoning, fumigation and systemic effects. It is quick to knock down pests, has a long residual effect period, and has a broad spectrum of insecticidal properties. I...
