Embodiment 1

[0023] The original drug (nitenpyram and pyridaben), various additives and fillers are fully mixed, and pulverized by an ultra-fine pulverizer to obtain a nitenpyram-pyridaben wettable powder. For example, the following formula can be adopted:

[0024] Nitenpyram 12.5%

[0025] Pyridaben 12.5%

[0026] Sodium lauryl sulfate (surfactant) 2%

[0027] White carbon black (filler) 5%

[0028] Vinylpyrrolidone (binder) 3%

[0029] Sodium lignosulfonate (dispersant) 6%

[0030] Attapulgite (filler) make up to 100%

[0031] The wettable powder of this embodiment is used to carry out the pest control experiment, and the control object is rice planthopper (test site Huai'an, Jiangsu, the field is a mixed population of brown planthopper and brown planthopper, and the proportion of brown planthopper is about 85%. After testing, the resistance of brown planthopper to imidacloprid level is neutral). The pest control experiment adopts spraying treatment, and spraying is started at the...

Embodiment 2

[0033] Except that the formula is different, this embodiment is basically the same as embodiment 1. The formula is as follows:

[0034] Nitenpyram 10%

[0035] Pyridaben 0.2%

[0036] Chaku powder (surfactant) 2%

[0037] Polyvinyl alcohol (dispersion binder) 4%

[0038] Sodium lignosulfonate (dispersant) 5%

[0039] Bentonite (filler) make up to 100%

[0040] The wettable powder of this embodiment was used to carry out the pest control experiment, and the control object was the rice leafhopper (test site Jiaxing, Zhejiang). Take the above-mentioned wettable powder and spray it according to 1500 times dilution, the control effect is 96.47% 72 hours after the application, the control effect of the control agent 10% nitenpyram water agent 1500 times, 20% pyridaben emulsifiable oil 1000 times, respectively is 86.35% , 74.62%.

Embodiment 3

[0042] Add the solvent, the original drug, and the emulsifier respectively, mix well, and if necessary, heat and dissolve in a hot water bath to obtain a transparent emulsifiable oil. For example, the following formula can be adopted:

[0043] Nitenpyram 1%

[0044] Pyridaben 15%

[0045] Nongru No. 500 (emulsifier) ​​8%

[0046] Nongru No. 700 (emulsifier) ​​3%

[0047] Ethanol (solvent) 8%

[0048] Xylene (solvent) make up to 100%

[0049] After dissolving, a transparent 16% nitenpyram·pyridaben emulsifiable concentrate was obtained.

[0050]The nitenpyram-pyridaben EC of this example was used to carry out the pest control experiment, and the control object was the rice white-winged leafhopper (the test site was Yiyang, Hunan). The above-mentioned EC was diluted and sprayed by 2000 times, and the control effect was 96.24% 72 hours after the application. The control effects of the control agent 10% nitenpyram water agent 1500 times and 20% pyridaben EC 1000 times were 8...

Abstract

The invention provides a pesticide composition and the application thereof, wherein the composition contains nitenpyram and pyridaben, and is used for controlling agricultural pests and acarus. The pesticide composition is prepared by the nitenpyram and the pyridaben, so that the composition shows excellent synergism within a certain preparation range, improves pest killing effect remarkably compared with a single preparation, simultaneously reduces use dosage of pesticide, application labor and cost, adverse effect to environment and pesticide residue, and has remarkable economic benefit and environmental benefit. In addition, action mechanisms of effective components of the nitenpyram and the pyridaben in the composition are different, so that the compositione combined by the nitenpyram and the pyridaben can delay or overcome drug resistance of pests, and prolong service life of the single preparation.

Description

technical field [0001] The invention relates to an insecticidal pesticide composition and application thereof, which are used for preventing and controlling pests and mites in agriculture. Background technique [0002] Rice planthopper is an important pest in rice production in my country. The harm of rice planthopper to rice mainly has three aspects: 1. Piercing and sucking rice juice. Adults and nymphs of rice planthoppers cluster in the lower part of the rice bushes, use their piercing and sucking mouthparts to penetrate into the rice stem tissue to suck juice, and when eating, the salivary glands secrete a toxic substance, which destroys the rice plant tissue and appears on the damaged stem. Many brown spots, when the damage is serious, the base of the grass is dark brown, and the whole plant gradually dies. When the number of insects is large, it often causes the rice to wither and die in a short period of time, and the rice fields become flat with dead stems. When a...
