Problems solved by technology

Diazinon is mostly used as a single agent alone, which cannot kill nematodes
[0006] Nematodes, mole crickets, grubs, cutworms and other pests often occur at the same time. The single application of thiazophos and diazinon cannot meet the requirements of agricultural production. The application cost is high, the dosage is large, and the environmental pollution is serious. Big

Embodiment 1

[0088] Example 1: 9% Thiazophosphine Diazinon (8% Thiazophosphine + 1% Diazinon)

[0089] Thiazophosphine Technical 8%

[0090] Diazinon technical 1%

[0091] Activated carbon 0.3%

[0092] Red brick particles make up to 100%

[0093] The red brick waste is crushed with a crusher, and then sieved. After the cycle of the above two processes, 20-50 mesh particles are finally selected for use. The original drug is put into a gravity-free mixer for adsorption and mixing by adopting a nozzle atomization dosing method, a granular carrier, and activated carbon. After the original drug is adsorbed, add activated carbon and stir again to obtain 9% thiazophosphine-diazinon granules.

The original drug is put into a gravity-free mixer for adsorption and mixing by adopting a nozzle atomization dosing method, a granular carrier, and activated carbon. After the original drug is well adsorbed, add activated carbon and stir again to obtain 10% thiazophosphine-diazinon granules.

[0106] This example is used to simultaneously control root-knot nematode disease on watermelon, watermelon grub. The specific control effect is shown in Table 4

Abstract

The invention discloses a pesticide composition for preventing and treating soil insects. The pesticide composition comprises following effective components: thiazole phosphine and diazinon, wherein the mass ratio of the thiazole phosphine to the diazinon is (64:1)-(1:32). Prepared from the thiazole phosphine and the diazinon in a compounding manner, the pesticide composition has good compatibility and a quite good synergistic interaction effect, and has the advantages of obviously improving the prevention and treatment effect on root-knot nematode and grub, reducing the total amount of used pesticide, lowering the use cost and also effectively preventing and treating soil insects including mole cricket, agrotis ypsilon and the like.

Description

technical field [0001] The invention relates to the technical field of pesticide production, in particular to an insecticide composition for controlling underground pests. Background technique [0002] Subterranean pests are omnivorous insects that live in the soil and damage the underground parts of plants, seeds, seedlings or main stems near the soil surface during their whole life or at a certain stage of their life. There are many types, mainly mole crickets, grubs, day lilies, cutworms, root maggots, etc. It is distributed all over China. Occurrence species vary from place to place, generally occur in dry-farmed areas, especially nematodes, mole crickets, grubs, needleworms, cutworms and root maggots are the most important. [0003] Nematode disease of plants is a plant disease caused by the attack and parasitism of plant parasitic nematodes. Injured plants can affect normal growth and development due to the invading nematodes absorbing nutrients in the body; the sec...
