Abstract
The invention relates to a herbicide compounded from nicosulfuron, bromoxynil octanoate and fluroxypyr. The technical scheme is as follows: the herbicide takes the nicosulfuron, the bromoxynil octanoate and the fluroxypyr as effective components, and the mass ratio of the nicosulfuron, the bromoxynil octanoate to the fluroxypyr is 1:(1-10):(0.5-3). The herbicide also comprises a stabilizing agent, a synergistic agent and/or a filling agent. The herbicide can be prepared into dosage forms, such as a dispersible oil suspending agent, wettable powder, a suspending agent, a water dispersible granule and soluble powder or missible oil, and the weight percentage of the effective components is 10%-50% in the dosage forms of the herbicide. The herbicide disclosed by the invention has obvious synergistic effect and the effect of increasing grass control speed after the nicosulfuron, the bromoxynil octanoate and the fluroxypyr are compounded, is low in toxicity and low in residue, enlarges the weed control spectrum, outstandingly reduces the dosage, the drug delivery times and the application cost and is favorable to prolonging the succession speed of a weed community and prolonging the service life of the herbicide.
Description
Technical field
The invention belongs to weed killer herbicide field, relate to particularly a kind of complex weedicide of preventing and kill off corn field annual weed that is mainly used in.
Background technology
The use of chemical herbicide is that vast farmers is in order to reduce labor intensity, can effectively control Farmland weed again, capture one of major measure of higher yield of crops, from now on for a long time in also inevitably by preventing and kill off weeds in field with chemical herbicide, reduce labor intensity, improve crop yield.
Corn is one of world's Three major grain crops, and cultivation history is long, is high-yield crop, is again nutritious forage crop, has " king of feed " laudatory title.The corn field weed emergence period is long, and generating capacity is large, and kind is many, in current corn field weed management system, weed killer herbicide still plays very important effect, moreover cornfield weeding is also a numerous and diverse farming activities, and chemical weed control can effectively be raised labour efficiency and reduce labor intensity.
Existing cornfield weeding mostly adopts the weed killer herbicide that contains a kind of active ingredient, and not only cost is higher, and herbicide spectrum is narrow, can not reach the object of once preventing and kill off multiple weeds.
Summary of the invention
The object of the invention is to: in a kind of active ingredient Control Weeds in Maize Field of independent use process, herbicide spectrum is not wide, be difficult to reach the practical problem of effectively preventing and kill off multiple weeds, provide a kind of and take nicosulfuron, bromoxynil octanoate and fluroxypyr as the composite weed killer herbicide of active ingredient.
The technical solution used in the present invention is: nicosulfuron and bromoxynil octanoate and fluroxypyr complex weedicide, take nicosulfuron, bromoxynil octanoate and fluroxypyr as active ingredient, and three's mass ratio is 1:1 ~ 10:0.5 ~ 3.
Above-mentioned complex weedicide, also comprises stabilizing agent, synergist and/or filler.
Above-mentioned complex weedicide, weed killer herbicide can be made formulations such as dispersibling oil-suspending agent, wetting powder, suspending agent, water dispersible granules, soluble powder or missible oil.In formulation of herbicide, the mass percent of active ingredient is 10-50%.
Above-mentioned complex weedicide, take urea as stabilizing agent, accounts for 0.5% of weed killer herbicide gross mass.Take Azone as synergist, account for 2% of weed killer herbicide gross mass.And at least two kinds of fillers: a kind of for agriculture breast 1601, account for 15% of weed killer herbicide gross mass, a kind ofly complement to 100% for turpentine-based vegetable oil.(turpentine-based vegetable oil is to extract from Chinese pine.Aspect environmental protection, have: pollution-free, the reproducible feature of resource.In agricultural chemicals, have: permeability is strong, plate-out ability is strong, and resistance of rainwater washing against can obviously improve drug effect, and quick-acting is obvious.）
The invention has the beneficial effects as follows: after the present invention is composite by nicosulfuron, bromoxynil octanoate and fluroxypyr, the multiple weeds of corn field are had to notable synergistic effect, and the dead speed of weeds is fast, has expanded herbicide spectrum, reduce dosage simultaneously, and delayed the speed of weeds population successions.
Accompanying drawing explanation
Fig. 1 is nicosulfuron and bromoxynil octanoate and fluroxypyr complex weedicide preparation were established figure.
