Benefits of technology

This patented inventive product helps fight insect attacks by reducing their number on crops or other plants while also being more effective than current products that only target one type of chemical called an organophosphorus compound (OPC). It reduces costs compared with traditional methods but still works well for certain types of harmful mite infested areas like rice fields where they are commonplace.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding new compounds useful for treatments involving harmful arthropods like weeds, dung bugs, wheatgrubs, rodents, birds, caterpots, grass pollinators, root slugs, rods, vegetation, and wildlife.

Embodiment 1

[0054] The present invention contains the emulsifiable concentrate preparation of the high-efficiency insecticide of benzoyl urea, pyridophos and thiamethoxam, and concrete composition is as follows (every part 1000g):

[0055] Benzoylurea: 10 parts; Pyridophos: 20 parts; Thiamethoxam: 20 parts;

[0056] The specific production steps of the emulsifiable concentrate preparation are first adding the active ingredients benzoyl urea, pyridophos-methyl, and thiamethoxam into the solvent according to the conventional procedures in the field to completely dissolve them, then adding emulsifiers and synergists and stirring evenly to form a uniform and transparent The oily liquid can be filled into the emulsifiable concentrate preparation of the composition of the present invention.

Embodiment 2

[0058] The present invention contains the suspending agent of the high-efficiency insecticide of benzoyl urea, pyridophos and thiamethoxam, and concrete composition is as follows (every part of 1000g):

[0059] Benzoylurea: 50 parts; Pyridophos: 40 parts; Thiamethoxam: 60 parts;

[0060] The specific production steps of this suspending agent are the conventional suspending agent preparation method in the art, first other auxiliary agents (dispersant, antifreeze agent, thickener, defoamer, penetration enhancer and pH value regulator) are mixed, Shear and mix evenly, add active ingredients benzoyl urea, pyridophos and thiamethoxam, and grind balls in a ball mill for 2 to 4 hours, so that the particle diameters are all below 5mm, and the composition of the present invention can be prepared suspension formulations.

Embodiment 3

Abstract

The invention relates to an efficient insecticide composition for killing agricultural pests. The efficient insecticide composition comprises the following components in parts by weight: 10-50 parts of benzoy urea, 20-40 parts of azamethiphos and 20-60 parts of thiamethoxam. The efficient insecticide composition disclosed by the invention has a remarkable synergetic effect, is capable of reducing the consumption of active ingredients, lowering the use cost, delaying the generation of pest resistance to insecticides, and effectively reducing environment pollution and pesticide residue, and has a remarkable effect of killing pests such as cossidae, aphids, psylla, grapholitha funebrana treitscheke, potato beetles, flies, cockroaches and various mites; meanwhile, the damage to the environment can be reduced.
