Embodiment 1

[0032] Take 25 grams of promethazine, add 10 milliliters of xylene (or acetone), stir to dissolve; add 10 milliliters of dimethylbenzene (or acetone), stir and dissolve; mix the two solutions, add 8 grams of tea saponin Pesticide synergist QB-10, 10 grams of emulsifier castor oil polyoxyethylene ether 0206B, stirred for 15 minutes, added the remaining amount of xylene (or acetone) to make a total mass of 100 grams, stirred for 20 minutes, stood still, and filtered , to obtain the herbicide compounded by the binary compound of protrazone and thalamin.

Embodiment 2

[0034] Take 8 grams of promethazine, add 10 milliliters of xylene (or acetone), stir and dissolve; add 30 grams of oxalane, add 20 milliliters of xylene (or acetone), stir and dissolve; mix the two solutions, add 15 grams of tea saponin Pesticide synergist QB-10, 10.5 grams of emulsifier castor oil polyoxyethylene ether 0206B, stirred for 15 minutes, added the remaining amount of xylene (or acetone) to make a total mass of 100 grams, stirred for 25 minutes, stood still, and filtered , to obtain the herbicide compounded by the binary compound of protrazone and thalamin.

Embodiment 3

[0036] Take 10 grams of procytine, add 20 ml of xylene (or acetone), stir to dissolve; add 20 ml of xylene (or acetone) to 25 grams of stable ketone, stir and dissolve; mix the two solutions, add 5.5 grams of tea saponin Pesticide synergist QB-10, 8 grams of emulsifier castor oil polyoxyethylene ether 0206B, stirred for 15 minutes, added the remaining amount of xylene (or acetone) to make a total mass of 100 grams, stirred for 30 minutes, stood still, and filtered , to obtain the herbicide compounded by the binary compound of protrazone and thalamin.

Abstract

The invention provides a prometryn and fluazifop-butyl binary complex herbicide and a preparation method thereof. The herbicide comprises the following components by mass: 8-25% of prometryn, 10-30% of fluazifop-butyl, 5-15% of synergist, 8-20% of emulsifier and the balance solvent. The preparation method comprises the following steps: mixing and stirring the prometryn and the solvent according to the mass ratio; mixing and stirring the fluazifop-butyl and the solvent; mixing and stirring the mixtures; adding the emulsifier together with the synergist to a reaction kettle to be stirred for 10-15min; then adding the balance solvent and stirring the mixture for 20-30min; and then carrying out standing, filtering, filling and sampling analysis, thus obtaining the finished product. The herbicide has high efficiency and broad spectrum, is used for pre-emergence soil spraying or post-emergence spraying after sowing such crops as cotton, soy beans, peanuts, pears, peaches, grapes, forestry seedlings, flax and the like, can realize that the crops are free from weeds in the whole growth period through one-time application of 80-100g per mu and has application cost 20.1-27.2% lower than that of the single prometryn or fluazifop-butyl respectively.

Description

technical field [0001] The invention relates to a herbicide and a preparation method thereof, in particular to a herbicide prepared by binary compounding of a triazine-type promethazin and a phenoxycarboxylic acid-type herbicide, and a preparation method thereof. Background technique [0002] Promethazine is a broad-spectrum herbicide, which is effective in controlling annual weeds in dryland crops. Pre-emergence and early post-emergence applications work best. Wenshade is a phenoxycarboxylic acid post-emergence herbicide, which is effective in controlling annual weeds and broad-leaved weeds in dryland crops. However, the single application of the two kinds of single doses cannot achieve no weed damage in the whole growth period of crops. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the above-mentioned herbicides cannot reach the problem of no weed damage in the whole growth period of the crops with one application,...
