Problems solved by technology

[0002] Piercing-sucking mouthparts pests are a common type of agricultural pests. They pierce plant tissues with needle-like stylets and absorb juices, causing the affected parts of plants to fade and turn yellow, causing malnutrition, organ wilting or curling deformities. Some of these pests spread plant viruses while harming plants, causing serious losses to farmers.
[0003] At present, due to the long-term continuous use of insecticides containing a single active component, pests develop resistance, poor quick-acting and short-lasting effect, the effect of use is not ideal, and repeated use will cause serious pollution to the ecological environment
Another way is to introduce new ingredients that have no cross-resistance to existing pesticide varieties, but the development cost of new ingredients is high and the development time is long

Embodiment 1

[0014] Weighing: Nitenpyram (pure) 2 parts

[0015] Zhong Dingwei (pure) 30 parts

[0016] NNO 8 servings

[0017] Sodium dodecylbenzenesulfonate 4 parts

[0018] White carbon black 2 parts

[0019] 3 parts ammonium sulfate

[0020] Diatomaceous earth Add up to 100 parts.

[0021] 32% Nitenpyram·Zobutacarb water-dispersible granules were prepared from the above-mentioned raw materials through the steps of superfine pulverization, mixing and granulation for conventional preparation of granules.

[0022] In this experimental example, the weight ratio of nitenpyram and secbucarb can be changed between 1:10~50 (example 1:10, 1:20, 1:30, 1:40, 1:50). The total weight component is still 32%, forming a new embodiment.

[0023] It is also possible to replace secbucarb with one of Isoprocarb, methomyl, methiocarb or carbosulfan to form a new embodiment.

Embodiment 2

[0025] Weighing: Nitenpyram (pure) 3 parts

[0026] Isoprocarb (pure) 25 parts

[0027] Emulsifier 34# 6 parts

[0028] Emulsifier NP-10P# 4 parts

[0029] 20 parts of toluene

[0030] Water is added to make up to 100 parts.

[0031] A 28% nitenpyram·isoprocarb emulsion in water was obtained by high-shear emulsification of the above raw materials.

[0032] In this experimental example, the weight ratio of nitenpyram and isoprocarb can be changed between 1: 10~50 (example 1: 10, 1: 20, 1: 30, 1: 40, 1: 50). The total weight component is still 28%, forming a new embodiment.

[0033] It is also possible to replace the isoprocarb with one of secbucarb, methomyl, methiocarb or carbosulfan to form a new embodiment.

Embodiment 3

[0035] Weighing: Nitenpyram (pure) 2 parts

[0036] Carbosulfan (purified) 40 parts

[0037] NNO 5 copies

[0038] Sodium lignosulfonate 6 parts

[0039] White carbon black 8 parts

[0040] Kaolin Add enough to 100 parts.

[0041] The above raw materials were conventionally prepared into wettable powders and mixed to prepare 42% Nitenpyram·Carbosulfan wettable granules.

[0042] In this experimental example, the weight ratio of nitenpyram and carbosulfan can vary between 1:10~50 (example 1:10, 1:20, 1:30, 1:40, 1:50), The weight composition of the two is still 42%, forming a new embodiment.

[0043] It is also possible to replace carbosulfan with one of secbucarb, isoprocarb, methomyl and methiocarb to form a new embodiment.

Abstract

The invention provides a desinsection composition which comprises nitenpyram and carbamate pesticide, wherein the weight ratio of the nitenpyram to the carbamate pesticide is between 1 to 1 and 1 to 100; the preference weight ratio of the nitenpyram to the carbamate pesticide is between 1 to 10 and 1 to 50, and the deinsection composition is mainly used for preventing and controlling homopteran pests. The desinsection composition has the advantages that the components are reasonable so that the preventing and controlling effects are obvious, the quick action is good and the persistent period is long; and the cost is saved, the insecticide resistance of pests is delayed, and the pollution to the environment is reduced.
