Embodiment 1

[0024] The contents of the following substances are all percentages by weight: nitratephos 40%, fenpyrafen 5%, dioctyl maleate sulfonate sodium 8%, cyclohexanone 5%, rosin-based vegetable oil 5% %, ethylene glycol 2%, xanthan gum 2%, silicone oil 0.1%, sodium benzoate 1%, deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, and after being uniformly stirred by high-speed shearing, a 45% nitrofos-pyrafenate emulsion in water can be prepared.

[0025] Use the above-mentioned 45% nitrofos-pyrafenate aqueous emulsion for the prevention and treatment of citrus scale insects: 45% nitropyrphos-pyridifen aqueous emulsion is applied at 300 mg a.i. / kg, and the citrus scale insects are treated 7 days and 14 days after the application. The control effects on citrus scale insects were 85.72% and 78.69% respectively; 40% nitrofos in water emulsion was applied at 300 mg a.i. / kg, and the control effects on citrus scale insects were 71.45% and 60.98% respe...

Embodiment 2

[0027] The contents of the following substances are all percentages by weight: nitropyron 12%, fenpyrafen 2%, Nongru 500# 5%, Nongru 700# 5%, ethyl acetate 5%, doublycidal 2%, Methylated vegetable oils make up to 100%. Mix the above-mentioned materials in proportion, stir and dissolve completely, and then 14% nitrofos-pyrafenate emulsifiable concentrate can be prepared.

[0028] Using the above 14% nitropyrid-pyridifen EC for the prevention and treatment of citrus psyllids: 14% nitropyrid-pyridifen EC was applied at 300 mg a.i. / kg, and the effects on citrus psyllids were treated 7 days and 14 days after the application. The control effects are 89.14% and 83.55% respectively; 12% nitrofos EC is 300mg

[0029] With a.i. / kg application, the control effects on citrus psyllids were 75.19% and 66.88% respectively at 7 days and 14 days after the drug application; 2% pyraclofen EC was applied at 80 mg a.i. / kg, and the control effects on citrus psyllids at 7 days and 14 days after dru...

Embodiment 3

[0031] The contents of the following substances are all percentages by weight: 16% of nitropyrrophos, 4% of pyrenzafen, 6% of lauryl polyoxyethylene ether phosphate, 4% of alkyl sulfate, and 2% of aluminum magnesium silicate. %, Ethylene Glycol 2%, C 10-20 Saturated fatty acid compound 0.1%, isothiazolinone 0.2%, deionized water make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 20% nitropyrrophos-pyrazafen suspension concentrate.

[0032] Use the above 20% nitropyrophos-pyridafen suspending agent to prevent and control citrus spider mite: 20% nitropyrphos-pyridifen suspending agent is applied at 300 mg a.i. / kg, and the effect on citrus red spider mites is 7 days and 14 days after the drug. The control effects on spiders were 96.31% and 88.62% respectively; 16% nitrofos suspension was applied at 300 mg a.i. / kg, and the control effects on citrus red spiders were 58.73% an...

Abstract

The invention discloses a pesticide composition with xiaochongthion and cyenopyrafen. The pesticide composition consists of effective active components, namely xiaochongthion and cyenopyrafen, whereinthe weight ratio of the xiaochongthion to the cyenopyrafen is (30:1)-(1:1). The pesticide composition disclosed by the invention is excellent in effect of preventing and treating scale insects, phylloxera, red spiders and the like on citrus trees and is long in effect lasting time and safe to citrus trees. After being compounded, the xiaochongthion and the cyenopyrafen have a remarkable synergistic function, the use amount of pesticides is reduced, the use cost is reduced, environment pollution is reduced, drug resistance of insects is delayed, and the service life of the pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a binary compound compounded with nitropyrphos and pyrazafen as effective active ingredients, which is mainly used in the prevention and control of pests on crops. Background technique [0002] Nitraphos: It is a systemic organophosphorus insecticide and acaricide with strong contact and stomach toxicity, and its mechanism of action is an inhibitor of acetylcholinesterase. It has a good control effect on pests such as citrus red spider mite, Yajian scale, cotton bollworm, vegetable tobacco budworm, diamondback moth and rice planthopper. [0003] Pyridofen: It is a new type of pyrazole acaricide. The mechanism of action is that the agent is metabolized into a hydroxyl form and activated to generate activity. This hydroxyl form inhibits mitochondrial efficiency by disrupting complex II in the respiratory electron transport chain. , thereby hindering electron tra...
