Embodiment 1

[0019] Example 1: 25% fenphos-bifenazate suspension concentrate.

[0020] Nitrophos 20%, Bifenazate 5%, Polycarboxylate 15%, Alkylphenol polyoxyethylene ether formaldehyde condensate sulfate 15%, Xanthan gum 2%, Glycerol 2%, Silicone oil 0.1%, deionized water makes up 100%. Mix the above-mentioned active ingredients, dispersant, wetting agent, thickener, antifreeze, defoamer and deionized water, disperse by high-speed shear, sand in a sand mill, and form a highly dispersed and stable water medium The suspension system can produce 25% fenphos-bifenazate suspension concentrate.

Embodiment 2

[0021] Example 2: 30% fenphos-bifenazate water emulsion.

[0022] Nitrophos 20%, Bifenazate 10%, Linseed Oil 20%, Castor Oil Polyoxyethylene Ether 10%, Polycarboxylate 10%, Sodium Sorbate 1%, Glycerol 1%, Deionized Water Make up 100%. Mix the above active ingredients, solvents, emulsifiers, dispersants and stabilizers to form an oil phase. The antifreeze is dissolved in water to form a water phase. Under the action of a shearing machine, slowly add the oil phase to the water phase and continue to shear approximately In 30 minutes, 30% fenphos-bifenazate water emulsion can be prepared.

Embodiment 3

[0023] Example 3: 40% fenphos-bifenazate microemulsion.

[0024] Nitrophos 15%, Bifenazate 25%, Cyclohexanone 20%, Styrylphenol Polyoxyethylene Ether 15%, Sodium Citrate 2%, Silicone 1%, Azone 2%, Deionized Water Make up 100%. Completely dissolve the active ingredients in a solvent, then add emulsifiers, stabilizers, penetrants, and synergists to mix evenly, and finally add deionized water, after fully stirring, 40% nitrophos-biphenyl can be obtained A hydrazine ester microemulsion.

Abstract

The invention discloses a pesticide composition containing Xiaochongthion and bifenazate. The pesticide composition contains a first active ingredient Xiaochongthion, a second active ingredient bifenazate and commonly-used auxiliary ingredients, wherein weight ratio of Xiaochongthion to bifenazate is 30:1-1:30, and the total weight of Xiaochongthion and bifenazate in the composition is 1-85 wt%. It shows through a lot of indoor and outdoor tests that the pesticide composition has an obvious synergic effect. Insecticidal spectrum is broadened. The pesticide composition can be used in controlling various insects in agriculture, such as red spider, whitefly, scale insect and the like. Meanwhile, usage amount of pesticides is reduced, residual quantity of pesticides on crops is minimized, environmental pollution is mitigated, and generation of pest resistance to insecticide is delayed.

Description

Technical field [0001] The present invention relates to a pesticide composition and its application field. Specifically, it is a pesticide composition with nitrofenphos and bifenazate as active ingredients, and is mainly used for the prevention and control of red spiders, whiteflies and scale insects in agriculture. . Background technique [0002] Nitrophos is an organophosphorus insecticide and its mechanism of action is an inhibitor of acetylcholinesterase. It has a good control effect on pests such as citrus red spiders, blue scale insects, cotton bollworm, vegetable tobacco budworm, diamondback moth and rice planthopper. [0003] Bifenazate is a new type of hydrazine ester compound whose mechanism of action is an antagonist of mites γ-aminobutyric acid (GABA). It is effective for all life stages of mites, has egg killing activity and knockdown activity on adult mites, and has a long lasting period of about 14 days. The recommended dosage is safe for crops. [0004] The issue ...
