Embodiment 1

[0022] Weigh 5g of spinosad, 20g of isoprocarb, 4g of calcium dodecylbenzenesulfonate, 3g of phenethylphenol polyoxyethylene ether, and xylene to 100g, and mix the above raw materials according to the conventional method of preparing emulsifiable concentrate Mix in the still, form the ethyl spinosad · isoprocarb emulsifiable concentrate that main active ingredient weight percentage content is 25%.

[0023] The sample that adopts embodiment 1 to carry out the field test of field control cotton bollworm, contrast agent is 60 grams per liter of spinosad SC and 25% isoprocarb WP, and concrete consumption is shown in Table 1, and water consumption per mu is 30kg 3 days, 7 days, 14 days, and 28 days results were checked after the medicine. The test results are shown in Table 1:

[0024] The field test result of table 1 example 1 sample to cotton bollworm

[0025]

[0026] As can be seen from Table 1, Example 1 has excellent quick-acting properties against cotton bollworms, and h...

Embodiment 2

[0028] Adopt the sample that embodiment 1 is equipped to carry out the field experiment of controlling rice brown planthopper in the field, contrast medicament is 60 grams / liter of spinosad SC and 25% isoprocarb WP, and concrete consumption is shown in Table 2, and water per mu is 30kg, medicine Check the results after 3 days, 7 days, 14 days, and 28 days. The test results are shown in Table 2:

[0029] Table 2 example 1 sample is to the field test result of rice brown planthopper

[0030]

[0031]

[0032] It can be seen from Table 2 that the sample of Example 1 has an excellent effect on rice brown planthopper, and has a relatively long duration of effect, and performs well in the field, and is an excellent agent for preventing rice brown planthopper.

[0033] The indoor synergistic test shows that: the compound of spinosad and isoprocarb has a significant synergistic insecticidal effect on cotton bollworm and rice brown planthopper; the field efficacy test also shows ...

Embodiment 3

[0035] Weigh 0.2g of spinosad, 20g of isoprocarb, 10g of lignin, 2g of sodium alkylnaphthalene sulfonate, add kaolin to 100g, mix the above raw materials in an ultrafine pulverizer, and form the main active ingredient by weight. Spinosad · Isoprocarb wettable powder with a content of 20.2%.

Abstract

A composite pesticidal composition comprising spinetoram and isoprocarb and uses thereof are disclosed. The composition adopts the spinetoram and the isoprocarb as pesticidal active components, wherein the weight ratio of the spinetoram to the isoprocarb being 0.1-80:0.5-80. The composition has a function of expanding the control spectrum and a synergetic function, reduces the pesticide using cost, can be prepared into emulsifiable concentrates, wettable powder, microemulsion, emulsion in water, suspension and water dispersible granules. The composition is used for control a plurality of pests, such as lepidoptera, hemiptera, hymenoptera and coleopteran.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic insecticidal composition containing spinosad and isoprocarb and an application thereof. Background technique [0002] Spinetoram, the structural formula is: [0003] [0004] XDE-175-J is a new spinosad insecticide produced by Dow AgroSciences and has received the first global registration, it can effectively control important pests on fruit trees and nuts, especially on fruit trees One of the thorny main pests of the apple moth. It is mainly used to control Lepidoptera larvae, thrips and leafminers, etc. It has good control effects on diamondback moth, beet armyworm, leafminer, thrips, Spodoptera litura and pod borer. [0005] Isoprocarb, chemical name: 2-(1-methylethyl) phenylmethyl carbamate, molecular formula: [0006] C 11 h 15 NO 2 , the structural formula: [0007] Isoprocarb mainly inhibits acetylcholinesterase on insects, but the insects ar...
