Problems solved by technology

[0008] However, rice planthoppers and aphids have gradually increased their resistance under the current long-term use of pesticides, and the effect of single-dose pesticides on pest control has gradually declined.
The inventor has found through research that the synergistic compounding of pesticides is an effective measure to expand the control spectrum and improve the control effect. So far, no insecticidal composition related to nitenpyram and thiacloprid has been found.

Embodiment 1

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

[0023] The rice stem dipping method was used for indoor synergistic bioassay. The resistant rice planthoppers were selected as the target pests. Each treatment was repeated 3 times, and each concentration was 60. The probability value method was used to calculate the toxicological regression of the resistant rice planthoppers. Equation and lethal concentration LC 50 , Use LC 50 The value is calculated by Sun Yunpei's method of co-toxicity coefficient, and the results are shown in Table 1:

[0026] It can be seen from Table 1 that the co-toxicity coefficient of the combination of nitenpyram...

Embodiment 2

[0032] Weigh 5g nitenpyram, 50g thiacloprid, 3g phenethylphenol polyoxyethylene ether phosphate, and agricultural milk 33 # 2g, alkylphenol polyoxyethylene ether 1g, xylene 13g, add water to 100g. The above raw materials are put into a mixing kettle for high-speed mixing according to the conventional method of preparing an aqueous emulsion to form an aqueous emulsion preparation with a mass percentage of 55% nitenpyram-thiacloprid aqueous emulsion.

Embodiment 3

[0034] Weigh 2g nitenpyram, 30g thiacloprid, 6g calcium dodecylbenzenesulfonate, 3g phenethylphenol polyoxyethylene ether phosphate, and agricultural milk 33 # 2g, alkylphenol polyoxyethylene ether 1g, cyclohexanone 10g, add water to 100g. The above raw materials are put into a mixing kettle according to the conventional method for preparing microemulsions and mixed to form a microemulsion preparation with a mass percentage of 32% nitenpyram-thiacloprid microemulsion.

[0035] The efficacy test for controlling rice brown planthopper in Example 3 was carried out. The control agents were 32% thiacloprid WP and 32% nitenpyram AS, diluted according to the dilution factor in Table 3, and checked for 2 days, 5 days and 10 days after treatment. The results of days, the processing results are shown in Table 3:

Abstract

The invention discloses a nitenpyram and thiacloprid-containing composite pesticide composition and application thereof. The pesticide composition comprises the nitenpyram and the thiacloprid serving as main active ingredients, wherein the weight ratio of the nitenpyram to the thiacloprid is 0.1-80:0.5-80. The pesticide composition can produce higher synergistic effect, overcome and delay the pesticide resistance of pests, has high pest killing speed and long effective duration, reduces the pesticide application cost and has more obvious prevention and control effect than that of a single pesticide. The pesticide composition can prevent and control hemiptera pests on crops, is particularly used for preventing and controlling rice planthopper and aphid and has more obvious effect than that of the single pesticide.

Description

Technical field [0001] The invention belongs to the field of pesticides, and specifically relates to a composite insecticidal composition containing nitenpyram and thiacloprid and its use. Background technique [0002] Nitenpyram (nitenpyram) is a neonicotinoid insecticide with the chemical name (E)-N-(6-chloro-3pyridylmethyl)-N-ethyl-N′-methyl-2 -Nitrovinylidene diamine. The structural formula is as follows: [0003] [0004] This medicine has a wide insecticidal spectrum and is widely used in agriculture and horticulture to control aphids, leafhoppers, thrips, planthoppers and other pests. It has a small dosage, low toxicity, and lasting efficacy. It is safe to use and safe for crops. It has a unique method for nicotinic acetylcholine receptors, which makes it difficult for pests to develop resistance and has excellent systemic and osmotic effects. However, the market price of this pesticide is relatively high. [0005] The chemical name of thiacloprid is (3-(6-chloro-3-pyridyl...
