Embodiment 1

[0021] Weigh 5g of spinosad, 20g of memocarb, 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 spinocidin · metolcarb emulsifiable concentrate that the weight percent content of main active ingredient is 25%.

[0022] The sample that adopts embodiment 1 to carry out the field test of field prevention and control cotton bollworm, contrast agent is 60 grams per liter of spinosad SC and 25% medicarb 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:

[0023] The field test result of table 1 example 1 sample to cotton bollworm

[0024]

[0025] As can be seen from Table 1, Example 1 has excellent quick-acting properties against cotton ...

Embodiment 2

[0027] 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 per liter of spinosad SC and 25% amecarb 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:

[0028] Table 2 example 1 sample is to the field test result of rice brown planthopper

[0029]

[0030]

[0031] 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.

[0032] Show through indoor synergistic test and measure: all have significant synergistic insecticidal action to cotton bollworm and rice brown planthopper by ethyl spinosad and methiocarb compound; Field efficacy test...

Embodiment 3

[0034] Take by weighing 0.2g spinosad, 20g memocarb, lignin 10g, sodium alkylnaphthalene sulfonate 2g, add to 100g with kaolin, mix the above raw materials in an ultrafine pulverizer to form the main active ingredient weight hundred Spinosad · Memocarb wettable powder with a content of 20.2%.

Abstract

The invention discloses a synergistic insecticidal composition containing spinetoram and metolcarb, and applications thereof. According to the synergistic insecticidal composition, spinetoram and metolcarb are taken as the main active ingredients, and weight ratio of spinetoram to metolcarb is 0.1-80:0.5-80. The synergistic insecticidal composition is capable of enlarging control spectrum, achieving synergistic effects, and reducing drug cost; can be made into missible oil, wettable powder, microemulsion, emulsion in water, suspending agent, and water dispersible granule; and is used for preventing and controlling a plurality of insects of 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 using spinosad and medicarb 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] Metolcarb, chemical name: 3-tolyl-N-methylcarbamate, molecular formula: C 9 h 11 NO 2 , the structural formula: [0006] Meprocarb has good contact and fumigation effects, strong knockdown power, and a persistence period of 3 to 4 da...
