Embodiment 1

[0020] Calculated according to weight percentage, the thickener is composed of 1% activated sludge, 60% hydroxyethyl cellulose and 39% stearic acid. The preparation method is: heating activated sludge, hydroxyethyl cellulose and stearic acid to Stir well at 60°C and cool to room temperature.

Embodiment 2

[0022] Calculated according to weight percentage, the thickener is composed of 5% activated sludge, 45% hydroxyethyl cellulose and 50% stearic acid, and the preparation method is: heating activated sludge, hydroxyethyl cellulose and stearic acid to Stir well at 80°C and cool to room temperature.

Embodiment 3

[0024] Active ingredient 10kg, fatty alcohol polyethylene glycol ether sodium sulfate 2kg, fast penetrating agent T2kg, sodium lignosulfonate 4kg, thickener 0.6kg of Example 1, silicone 0.1kg, 81.3kg ethyl oleate. The active ingredients include 3 kg of disulfuron-methyl, 3 kg of florasulam and 4 kg of salmazone.

[0025] Preparation:

[0026] 1) Add the active ingredient active ingredient, sodium fatty alcohol polyglycol ether sulfate, sodium lignosulfonate, silicone and ethyl oleate into the mixing kettle, and mix the materials fully and evenly under high-shear stirring to obtain mixture A;

[0027] 2) Then add the fast penetrating agent T and the thickener of Example 1 to the mixture A, stir continuously, grind the mixture into a sand mill, and sand for 2 hours.

Abstract

The invention provides a post-emergence compound herbicide for wheat fields. The post-emergence compound herbicide is prepared from, by weight, 10-60% of active components, 2-10% of a wetting agent, 2-8% of a dispersing agent, 1-6% of a penetrating agent, 0.5-6% of a thickening agent, 0.1-1% of an defoaming agent and the balance ethyl oleate, wherein the active components include mesosulfuron, florasulam and tralkoxydim in a weight ratio of 1-15:1-15:2-20, and the thickening agent is a mixture of activated sludge, hydroxyethyl cellulose and stearic acid. The post-emergence compound herbicide is capable of not only controlling gramineous weeds in the wheat fields but also controlling broadleaved weeds and is high in suspension stability to meet requirements of high-altitude low-temperature regions.

Description

technical field [0001] The invention belongs to the technical field of herbicides, in particular to a post-emergence compound herbicide for wheat fields. Background technique [0002] Pesticide oil suspension concentrate is a dispersion of oil-insoluble solid pesticide or immiscible liquid pesticide in oil. From the perspective of production, it is generally required that the original drug is solid at room temperature, and its solubility in the dispersion medium (20 ° C ~ 40°C) less than 100mg / L of pesticide varieties. The advantage of pesticide oil suspension concentrate is that it can be uniformly mixed and dispersed with oil in any proportion, easy to use, not easy to pollute the environment, and can be sprayed directly or after dilution. The processing and preparation method can be made into a highly dispersed and continuous phase suspension by wet pulverization. The average particle size of the particles is generally below 3 microns, which greatly improves the suspensi...
