Problems solved by technology

The pesticides commonly used in rice borer control in this area, such as isaminothiamine, are not registered on rice due to their high toxicity to humans and animals, and their use is prohibited; However, the lack of insecticides that have a high effect on rice borer borers in production is also a new problem that farmers urgently need to solve

Embodiment 1

[0040] Example 1: 15% Fenpyramid · Emamectin benzoate EC

[0041] Weighing: 13.78g of 98% pyrenpyrrole original drug, 1.6g of 94% emamectin benzoate original drug, 10g of dimethylformamide (cosolvent), tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) 10g, xylene (solvent) was added to 100g.

[0042] Active ingredients, solvents and emulsifiers are sequentially added into the mixing tank according to the formula, and stirred evenly to prepare 15% Fenpyramid · emamectin salt EC (fenpyran: emamectin 9:1).

[0043] This example is used to control rice borer borer and rice leaf roller. The test was carried out according to the "Pesticide Field Test Guidelines" (GB / T17980.1-2000, GB / T17980.2-2000). Add water according to the test dose (600kg / hm 2 ) was sprayed with a manual sprayer, and the control effect was investigated 25 days after application, and the results were shown in 4.

Embodiment 2

[0047] Example 2: 25% Fenpyramid · Emamectin Salt SC

[0048] Weighing: 24.285g of 98% tonamiprole former drug, 1.27g of 94% emamectin benzoate former drug, 5g of sodium methylnaphthalenesulfonate formaldehyde condensate (wetting dispersant), 2.0g of xanthan gum (thickener), Ethylene glycol (antifreeze) 2.0g, silicone oil (defoamer) 1g, water to make up to 100g.

[0049] Add the original drug of pyrenpyrid and emamectin benzoate into water, stir in a stirring tank until it becomes a homogeneous liquid, add the wetting dispersant and stir evenly; slowly add the thickener diluted with water, antifreeze under mechanical stirring at 60-120rpm / min agent, antifoaming agent, make up to 100ml with water, adopt air compression pipeline to transport feed liquid during grinding, adopt 4 sets of sand mills in series (filling fine zirconia beads and coarse zirconia beads) to carry out continuous sand milling, and make 25 % Fenpyramid · emamectin salt SC (fenpyran: emamectin salt 20:1).

Embodiment 3

[0054] Example 3: 31% Fenpyramid · Emamectin Diamectin EW

[0055] Take by weighing: 30.61g of the former medicine of 98% tonamiprole, 1.064g of the former medicine of 94% emamectin benzoate, 15g of xylene (solvent), 6g of tristyrylphenol polyoxyethylene ether phosphoester (emulsifier), propylene glycol (antifreeze agent) 3g, polydimethylsiloxane (defoamer) 0.5g, and water to make up to 100g.

[0056] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix antifreeze and defoamer with water to form a water phase; under high-speed stirring (180-200rpm / min), mix the oil phase and The water phases were mixed to prepare 31% Fenpyramid · Emamectin Salt EW (Fenpyran: Emamectin Salt 30:1).

[0057] This embodiment is applied to pear trees to control pear borer, pear star caterpillar, hawthorn spider mite and aphid. The test was carried out according to the "Pesticide Field Test Guidelines" (GB / T17980.9-2000, GB / T17980.11-2000). Add water ac...

Abstract

The invention relates to proportion and application of a pesticide composition. The active constituents of the pesticide composition provided by the invention comprise tolfenpyrad and emamectin benzoate. By weight percentage, the content of tolfenpyrad is 60%-1%, and the content of emamectin benzoate is 1%-30%. The ratio of tolfenpyrad and emamectin benzoate is 50:1-1:50, and the preferable ratio is 20:1-1:20. The pesticide composition provided by the invention has broad pesticide spectrum, strong systemic property, good quick-acting property and long acting period, is environment-friendly and facilitates reducing the dosage of pesticide and environmental pollution, and can effectively delay the pesticide resistance of injurious insects. The synergistic pesticide composition is applicable to the comprehensive control of injurious insects and mites of paddy rice, vegetables and fruit trees and can comprehensively protect the crops.

Description

technical field [0001] The invention relates to an insecticide composition and its application, in particular to a pesticide composition containing tolfenpyrad and its application for controlling crop pests and harmful mites. Background technique [0002] There are many insecticides or acaricides at present, but often the insecticides do not have acaricidal activity or have very low acaricidal activity, and the acaricides have no insecticidal activity or have unsatisfactory insecticidal activity; The pesticide is affected by the insecticidal spectrum, and it is often effective against one pest or mite, but not ideal for other pests or mite. And in many cases, both harmful insects and harmful mites are harmful to crops, and there is not only one kind of harmful insects or harmful mites. Therefore, to control multiple pests or mites on crops, farmers either repeat applications or choose to tank mix different insecticides or acaricides. However, farmers tank-mix insecticides ...
