Abstract
The invention discloses a kind of beet ground complex weedicide, comprise following component, each weight percentages of components is: metamitron 20 ~ 35%; Ethofumesate 15 ~ 35%; Dispersant 3 ~ 5%; Synergist 2 ~ 8%; Thickener 3 ~ 6%; Water surplus.Also disclose the preparation method of this kind of beet ground complex weedicide.Beet ground of the present invention complex weedicide is used for beet ground, more general weed killer herbicide single dose, and have notable synergistic effect, usage amount reduces greatly, and above the average age for marriage malignant weed can be prevented and kill off, broad weed-killing spectrum, the lasting period is long, a drug whole season, preparation took water as carrier, safety and environmental protection without crop smothering.And with low cost, production process is simple, and safety, weeding scope wide spectrum, especially has favorable effect to above the average age for marriage malignant weed.
Description
Technical field
The invention belongs to technical field of pesticide preparations, relate to a kind of beet ground complex weedicide, also relate to the preparation method of this kind of new composite herbicidal formulations in cotton field.
Background technology
Beet is that one is of high nutritive value, purposes is wide, the high crop of breeding and simple cultivation, the main sugar source economic crops except sugarcane, also can be used as feed and eat, weeds are of a great variety on beet ground, have a strong impact on Sugarbeet Yield and quality, and the weed killer herbicide single dose that usual market is sold can not good management of weeds, the present invention is used for beet ground and has notable synergistic effect, usage amount reduces greatly, and can prevent and kill off above the average age for marriage malignant weed, broad weed-killing spectrum, lasting period is long, a drug whole season, preparation took water as carrier, safety and environmental protection without crop smothering.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of beet ground complex weedicide, and safety, weeding scope wide spectrum, especially has favorable effect to above the average age for marriage malignant weed.
Another object of the present invention is to provide the preparation method of this kind of beet ground complex weedicide, simple to operate, with low cost.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of beet ground complex weedicide, and comprise following component, each weight percentages of components is:
In the present invention, metamitron belongs to Triazinone selectivity preemergence herbicide, absorbing, being transported in leaf, being played herbicide effect by the Hill reaction of inhibited photosynthesis mainly through plant root.Ethofumesate belongs to oxime herbicide.
Add dispersant, synergist, thickener be in harmonious proportion, for the more general weed killer herbicide single dose in beet ground, have notable synergistic effect, usage amount reduces greatly, and above the average age for marriage malignant weed can be prevented and kill off, broad weed-killing spectrum, the lasting period is long, a drug whole season, preparation took water as carrier, safety and environmental protection without crop smothering.
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
Preferably, described dispersant is at least one in aliphatic alcohol sulfate, alkyl biphenyl ether sulfonic acid sodium, lignosulfonates.
Preferably, described synergist is at least one in polymerization of carboxylic acid sodium, fatty acid ester sulphate, sorbitol anhydride fatty acid APEO.
Preferably, described thickener is at least one in xanthans, gelatin, polyvinyl alcohol, polyacrylamide.
The preparation method of this kind of beet ground complex weedicide, comprises the following steps successively:
Step one, dispersant is soluble in water, obtain aqueous dispersant;
Step 2, add in aqueous dispersant by metamitron, mixing, sand milling, obtains mixed slurry;
Step 3, by ethofumesate and synergist mixing, sand milling under 10 ~ 20 DEG C of conditions, obtains synergist compound;
In the mixed slurry that step 4, synergist compound input step 2 step 3 obtained obtain, then add thickener, mix;
Step 5, filtration, be up to the standards and obtain beet ground complex weedicide.
Compared with prior art, advantage of the present invention is: beet ground of the present invention complex weedicide is used for beet ground, more general weed killer herbicide single dose, have notable synergistic effect, usage amount reduces greatly, and above the average age for marriage malignant weed can be prevented and kill off, broad weed-killing spectrum, the lasting period is long, and a drug whole season is without crop smothering, preparation take water as carrier, safety and environmental protection.And with low cost, production process is simple, and safety, weeding scope wide spectrum, especially has favorable effect to above the average age for marriage malignant weed.
Below in conjunction with embodiment, the invention will be further described:
