Problems solved by technology

But acetamiprid is not effective against rice planthopper
[0008] Rice planthoppers and aphids have gradually increased their resistance under the current long-term medication conditions, and the effect of single-dose pesticides on pest control has gradually declined. The inventors

Example Embodiment

[0021] Example 1:

[0022] Nitenpyram and acetamiprid were weighed and formulated into nitenpyram·acetamiprid EC with a main active ingredient mass percentage of 30% by conventional preparation methods in different proportions. The specific ratios are shown in Tables 1 and 2.

[0023] The rice stem dipping method was used for indoor synergistic bioassay, and the resistant rice planthopper was selected as the target pest. Each treatment was repeated 3 times, and each concentration treated 60 heads. 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient:

[0024] Table 1 The virulence determination of nitenpyram and acetamiprid compound and single dose of resistant rice planthopper.

[0025]

[0026] It can be seen from Table 1 that the compound of nitenpyram and acetamiprid has a co-toxicity coefficient greater than 120, showing a good synergistic effect.

[0027] Select the resistant wheat aphids as the target pests. Use the method of soaking insects and soaking le...

Example Embodiment

[0039] Example 2:

[0040] Weigh 0.5g nitenpyram, 10g acetamiprid, 4g calcium dodecylbenzene sulfonate, 3g phenethylphenol polyoxyethylene ether, and xylene to 100g, put the above raw materials into the mixture according to the usual method of preparing emulsifiable concentrates Mix in the kettle to form a 10.5% nitenpyram·acetamiprid EC.

Example Embodiment

[0041] Example 3:

[0042] Weigh 2g nitenpyram, 8g acetamiprid, emulsifier 1602 # 4g, emulsifier 500 # 2g, N-methylpyrrolidone 4g, isopropanol 6g, xylene 3g, the balance is water, put the above raw materials into the mixing kettle according to the conventional method of preparing microemulsion, and mix to form 10% nitenpyram·acetamiprid Microemulsion.

Abstract

The invention discloses a synergistic insecticidal composition containing nitenpyram and acetamiprid, and application thereof. The synergistic insecticidal composition takes the nitenpyram and the acetamiprid as main active ingredients, wherein the weight ratio of the nitenpyram to the acetamiprid is 0.1-80:0.1-70. The insecticidal composition can realize relatively higher synergy, overcome and retard the resistance of insects to pesticides, ensure high insecticidal rate and long effective duration, reduce the application cost and prevent and control hemiptera insects, and is particularly used for preventing and controlling nilaparvata lugens and wheat aphids with effects remarkably better than that in the independent use of the nitenpyram and the acetamiprid.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic insecticidal composition with nitenpyram and acetamiprid as main active ingredients and an application thereof. Background technique [0002] Nitenpyram is a neonicotinoid insecticide with the chemical name (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2 - Nitroethylenediamine. The structural formula is as follows: [0003] [0004] The drug has a wide insecticidal spectrum, and is widely used in agriculture and horticulture to prevent and control aphids, leafhoppers, thrips, planthoppers and other pests. It has low dosage, low toxicity, long-lasting drug effect, no harm to crops, and is safe to use; Based on the nicotinic acetylcholine receptor, the method is unique, pests are not easy to develop resistance, and it has excellent systemic and osmotic effects. The market prospect is relatively broad, but the price of its commercially available raw drug...
