Embodiment 1

[0020] Nitenpyram and etofenprox were weighed and prepared in different proportions according to conventional preparation methods to prepare nitenpyram·methofenprox EC with a main active ingredient mass percentage of 30%. See Tables 1 and 2 for specific ratios.

[0021] Indoor synergistic bioassay was carried out by rice stem dipping method, and the resistant rice planthopper was selected as the target pest. 50 The co-toxicity coefficient was calculated according to Sun Yunpei method, and the results are shown in Table 1:

[0022] Table 1. Indoor toxicity test of nitenpyram-etoproxil compound and its single dose against rice planthopper

[0023]

[0024] The data in the table shows that the mixture of nitenpyram and etofenprox has a synergistic effect on rice brown planthopper, and the co-toxicity coefficients of the three ratios listed in the table are all far greater than 120, so nitenpyram and etofenprox Mixing has a significant synergistic effect.

[0025] Indoor syn...

Embodiment 2

[0039] Weigh 1g of nitenpyram and 9g of etofenprox and dissolve in 8g of xylene, then add 1g of ethylene glycol and 5g of disodium alkylphenol polyoxyethylene ether sulfosuccinate, and stir evenly. The above solution is slowly poured into the remaining amount of water, and fully stirred to form a 10% nitenpyram-etoproxil emulsion in water.

Embodiment 3

[0041] Dissolve 5g of nitenpyram and 5g of etofenprox in 8g of xylene, then add 1g of ethylene glycol and 5g of disodium alkylphenol polyoxyethylene ether sulfosuccinate, and stir evenly. The above solution is slowly poured into the remaining amount of water, and fully stirred to form a 10% nitenpyram-etoproxil emulsion in water.

Abstract

The invention discloses a synergistic pesticidal composition containing nitenpyram and ethofenprox and an application thereof. The synergistic pesticidal composition adopts the nitenpyram and the ethofenprox as the main active ingredients, wherein the weight ratio of the nitenpyram to the ethofenprox is (0.1-80): (0.1-60). The synergistic pesticidal composition containing the nitenpyram and the ethofenprox can be used for preventing and controlling resistant hemiptera injurious insects, and has obviously preventing and controlling effect on wheat aphids and rice planthopper. The pesticidal composition can generate higher synergy, overcomes and delays the drug resistance of the injurious insects, and has the advantages of fast insecticidal speed and long residual activity; and by using the synergistic pesticidal composition, the pesticide cost is reduced, and the prevention and control effect is obviously superior to that of the single dosage.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to an insecticidal composition with nitenpyram and etofenprox as main active ingredients and an application thereof. Background technique [0002] Nitenpyram, the chemical name is (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, and hemiptera pests. It has low dosage, low toxicity, and long-lasting drug effect. It has no harm to crops and is safe to use; the effect of the drug 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 its market price is relatively high. [0005] Etofenprox is a kind of p...
