Embodiment example

[0040] 1. Preparation Example 1

[0041] Weigh 4% penoxsulam, 12% promethazone, 10% mesotrione, 12% xylene, 6% fatty alcohol polyoxyethylene ether, 0.3% silicone oil, 3% penetrant JFC, deionized Water to make up the balance. Dissolve penoxsulam and mesotrione in xylene, add fatty alcohol polyoxyethylene ether and stir evenly to form an oil phase, add the oil phase to the deionized water in which promethazin has been dissolved, and then add other additives, Stir evenly to make 26% penoxsulam·prometon·mesotrione aqueous solution.

Embodiment 2

[0043] Weigh 9% penoxsulam, 1% promethazone, 5% mesotrione, 16% methanol, 8% calcium dodecylbenzenesulfonate, 0.4% hexanol, 4% azone, deionized Water to make up the balance. Dissolve penoxsulam and mesotrione in methanol, add calcium dodecylbenzenesulfonate and stir evenly to form an oil phase, add the oil phase into the deionized water in which promethazin has been dissolved, and then add other additives , Stir evenly, can make 15% penoxsulam · promethazin · mesotrione aqueous solution.

Embodiment 3

[0045] Weigh 25% penoxsulam, 15% promethazine, 10% fluroxypyr methyl ester, 15% n-butanol, 7% sorbitan monostearate, 0.5% octanol, 3.5% High goldthinone, deionized water to make up the balance. Dissolve penoxsulam and fluroxypyr in n-butanol, add sorbitan monostearate and stir evenly to form an oil phase, add the oil phase into the deionized water in which promethazine has been dissolved, Then add other additives and stir evenly to prepare a 50% penoxsulam·profenazin·chlorfluroxymethyl aqueous solution.

[0046] 4. Preparation Example 4

[0047] Weigh 25% penoxsulam, 15% promethanone, 10% tembotrione, 15% n-butanol, 7% sorbitan monostearate, 0.5% octanol, 3.5% genthilon , make up the balance with deionized water. Dissolve penoxsulam and sulfone in n-butanol, add sorbitan monostearate and stir evenly to form an oil phase, add the oil phase into the deionized water in which promethazine has been dissolved, and then add other additives , Stir evenly, then you can make 50% pen...

Abstract

The invention discloses a weeding composition containing penoxsulam and prometryn and application thereof. The active component of the weeding composition is prepared from penoxsulam, prometryn and aHDDP inhibitor, wherein the weight ratio of penoxsulam to prometryn to HDDP inhibitor is (0.1-50) to (0.1-50) to (0.1-50). The composition can be prepared to be water agents, suspension agents, suspoemulsions, dispersible oil suspension agent, wettable powder, water dispersible granules, particles and microcapsule suspension agents which are agriculturally allowable. The composition is reasonablein component and has the good weeding effect, meanwhile, the activity and the weeding effect of the composition are not simply superposition of the activity of the components, compared with existing simplex preparations or binary compounded preparations, the weeding composition has the outstanding weeding effect and the remarkable synergism, the dosage is reduced, the weed controlling spectrum isenlarged, and the weeding composition is safe to the crop.

Description

Technical field: [0001] The invention relates to a herbicidal composition, which is composed of active components penoxsulam, protractor, HDDP inhibitor and auxiliary components, and belongs to the technical field of compound pesticides. Background technique: [0002] my country has a long history of planting rice and has a vast territory. It is one of the main rice producing countries in the world. The weeds that harm rice fields mainly include barnyardgrass, daughter daughter, paspalum, crabgrass, foxtail, goosegrass, oat grass, wild oats and other gramineous weeds; Broad-leaved weeds such as Serving Vegetables, Festival Vegetables, Thin Beetle Leaf, Hollow Lotus Seed Grass, and Annual Capsules, and Sedges such as Alien Sedge, Broken Rice Sedge, Cow Felt, Sunshine Buddha Grass, Cyperus Cyperi, and Water Centipede Therefore, it is one of the main tasks of the pesticide formulation workers to develop an effective rice field herbicide. [0003] The common name of penoxsulam...
