Abstract
The invention discloses a compound weedicide for beet fields, which comprises the following components in percentage by weight: 20-35% of metamitron, 15-35% of ethofumesate, 3-5% of dispersant, 2-8% of synergist, 3-6% of thickener and the balance of water. The invention also discloses a preparation method of the compound weedicide for beet fields. The novel compound weeding preparation for beet fields is used for beet fields, and has an obvious synergistic action and lower consumption as compared with a common single weedicide; the novel compound weeding preparation for beet fields can prevent and remove elder worst weed, has the characteristics of wide weed control spectrum and long duration time, and can ensure no weed for the whole season after being applied once; and the preparation uses water as the carrier, and thus, is safe and environment-friendly. The novel compound weeding preparation for beet fields has the advantages of low cost, simple production procedure, high safety and broad weed control spectrum, and especially has favorable preventive effects on elder worst 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, breed and cultivate easy high crop, the main sugar source economic crops except sugarcane, also can be used as feed and edible, beet ground weeds are of a great variety, have a strong impact on Sugarbeet Yield and quality, the well management of weeds of weed killer herbicide single dose of conventionally selling on market, the present invention has notable synergistic effect for beet ground, 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, whole season of a drug is without crop smothering, and preparation is take water as carrier, safety and environmental protection.
Summary of the invention
Technical problem to be solved by this invention is just to provide a kind of beet ground complex weedicide, safety, and 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, comprise following component, and each weight percentages of components is:
In the present invention, metamitron belongs to Triazinone selectivity preemergence herbicide, mainly by plant root, absorbs, and being transported in leaf, by the Hill reaction of inhibited photosynthesis, plays herbicide effect.Ethofumesate belongs to oximes weed killer herbicide.
Add dispersant, synergist, thickener to be in harmonious proportion, for beet more general weed killer herbicide single dose, there is 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, the lasting period is long, whole season of a drug is without crop smothering, and preparation is take water as carrier, safety and environmental protection.
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
Preferably, each weight percentages of components is:
