Embodiment 1

[0015] Example 1: 30.5% fenazazafen · tebufenpyrad wettable powder (fenazazafen: tebufenpyrad = 60:1)

[0016] 30.30g of fenazaquin, 0.53g of tebuflufen, 2g of sodium lauryl sulfate (wetting agent), 3g of sodium lignosulfonate (dispersant), 5g of NNO (dispersant), and kaolin to make up to 100g.

[0017] The active ingredients, various additives and fillers are fully mixed in proportion, and then pulverized by a superfine pulverizer to obtain a wettable powder.

Embodiment 2

[0018] Example 2: 62% fenazazafen·pyrazafen water dispersible granules (fenazazafen: tebufenpyrad=30:1)

[0019] Fenazazafen 60.60g, Tebuzafen 2.10g, NNO (dispersant) 5g, Sodium lignosulfonate (dispersant) 5g, Sodium lauryl sulfate (wetting agent) 2g, Magnesium aluminum silicate (disintegration agent) agent) 2g, diatomaceous earth supplemented to 100g.

[0020] The active ingredients, additives and fillers are uniformly mixed according to the proportion of the formula, crushed into a wettable powder by airflow, and then a certain amount of water is added to mix and extrude to granulate, and the water-dispersible granule product is obtained after drying and sieving.

Embodiment 3

[0021] Example 3: 21% fenazazafen·pyrazafen suspension concentrate (fenazazafen: tebuzafen = 20:1)

[0022] 20.20g of fenazaquin, 1.05g of tebufenpyrad, 4g of lignosulfonate (dispersant), 4g of ethylene glycol (antifreeze), 3g of bentonite (thickener), 0.4g of silicone oil (defoamer), Make up to 100g with deionized water.

[0023] Add the pre-crushed original medicine and carrier, dispersant, defoamer, thickener, etc. into a sand mill, grind it finely, and then mix it through high-speed shearing to obtain a suspension.

Abstract

The invention discloses a pesticide combination comprising the active ingredients including fenazaquin and tebufenpyrad in a mass ratio of 60:1-1:60. By combining the fenazaquin and the tebufenpyrad, the combination has obvious synergy effect, can reduce the dosage of the active ingredients and the pesticide application frequency, and is conductive to retarding the drug resistance of mites. The combination of the invention can be used for controlling various mites on the crops and the horticultural crops, is especially suitable for controlling panonychus ulmi, tetranychus cinnabarinus and tetranychus urticae koch and can simultaneously control homopteran and hemiptera pests on the crops.

Description

technical field [0001] The invention relates to a pesticide composition, specifically a pesticide composition containing fenazaquin, and the application of the composition in the control of agricultural and horticultural crop acarid pests. Background technique [0002] Acarid pests are prone to develop resistance to acaricides due to their multiple generations, strong reproductive ability, and high degree of selfing. However, farmers are accustomed to continuous use of a single acaricide with good acaricidal effect, resulting in serious resistance to a variety of acaricides in a short period of time and thus losing their use value. The combination of acaricides with different action mechanisms is one of the effective ways to solve the problem of resistance of harmful mites and to use acaricides efficiently and sustainably. [0003] Fenazaquin, a quinoline acaricide, has a good control effect on citrus trees and apple tree spider mites, has a long duration of action, and is ...
