Problems solved by technology

It has a good effect on Phosphoptera larvae, and has a good control effect on Homoptera, Hemiptera and other pests, but it is ineffective against mites. It is suitable for cotton, fruit trees, tea trees, soybeans, sugar beets and other crops. Pest resistance to the drug is on the rise for longer periods of use
[0006] At present, the resistance of Hemiptera pests is gradually increasing, and the effect of single-dose pesticides on pest control is gradually declining. There is no effective preparation for the control of Hemiptera pests.

Embodiment 1

[0019] Weigh nitenpyram and beta-cypermethrin, and use conventional preparation methods to prepare nitenpyram and beta-cypermethrin in different proportions to prepare nitenpyram and beta-cypermethrin emulsifiable concentrate with a mass percentage of 40%. The specific proportions are shown in the table 1, 2.

[0020] The indoor synergistic bioassay was carried out by dipping leaves and insects, and the resistant cotton aphid was selected as the target pest. Each treatment was repeated 3 times, and the LC 50 Calculate the co-toxicity coefficient according to Sun Yunpei's method:

[0021] Table 1. Indoor toxicity determination of nitenpyram and beta-cypermethrin synergistic insecticidal composition and its single-dose resistant cotton aphid:

[0022]

[0023] The data in the table shows that nitenpyram and beta-cypermethrin have a synergistic effect on cotton aphids after mixing, and the co-toxicity coefficients of the three proportions listed in the table are all greater t...

Embodiment 2

[0038] Weigh 1g of nitenpyram and 9g of beta-cypermethrin and dissolve in 8g of xylene, then add 1g of ethylene glycol and 5g of disodium alkylphenol polyoxyethylene ether sulfosuccinate, and stir evenly. Slowly pour the above solution into the remaining amount of water and fully stir to prepare a 10% nitenpyram·beta-cypermethrin aqueous emulsion.

Embodiment 3

[0040] Take by weighing 8g nitenpyram, 2g beta-cypermethrin, sodium lignosulfonate 8g, sodium lauryl sulfate 2g, ammonium sulfate 5g, polyvinyl alcohol 5g, borax 2g, kaolin 28g, with the above raw materials Methods Prepare 10% nitenpyram·beta-cypermethrin water dispersible granules.

Abstract

The invention relates to a synergistic pesticidal composition containing nitenpyram and high-efficient cypermethrin and application thereof. The synergistic pesticidal composition comprises the following main active ingredients: nitenpyram and high-efficient cypermethrin, wherein the weight ratio of the nitenpyram to the high-efficient cypermethrin is (0.1-80):(0.1-50). The pesticidal composition can play a role of collaboration and synergy, and has the advantages that the injurious insect resistance to drugs is overcome and delayed, the insecticidal speed is quickened, and the pharmacy cost is reduced. The composition provided by the invention can be used for preventing and curing hemiptera insects, and effect is obviously better than that of the siple dosage use.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a synergistic insecticidal composition containing nitenpyram and beta-cypermethrin and its application. 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 toxicity, long-lasting drug effect, no harm to crops, and is safe to use; Acetylcholine receptors have a unique way, pests are not easy to develop resistance, and have excellent systemic and osmotic effects, but the drug is expensive. [0005] Cypermethrin is a pyrethroid insecticide with contact and stomach toxicity. It has a wide insecticidal spectrum, rapid drug effect, stable to light and heat, and ...
