Abstract

A herbicide for wheat field is prepared from thifensulfuron-methyl, fluroxypyr, carrier, surfactant, disperser and/or agricultural auxiliary. Its advantages are high effect and short residual period (one month).

Description

A kind of wheat paddock weed killer herbicide
Technical field
The present invention relates to a kind of wheat paddock weed killer herbicide.
Background technology
Along with society develops fast, science and technology further improves.The peasant is to the continuous understanding of weed killer herbicide, use constantly.At present the kind of wheat paddock weed killer herbicide also changes taking place, and the less important weeds of wheat paddock have been developed into main weeds.As wartwort (mao mao's eye), clearvers has been the main weeds of wheat paddock, and is difficult to control.Along with the increase of dosage, the pesticide resistance that makes weeds is in continuous reinforcement simultaneously.Existing tribenuron-methyl+fluroxypyr (ester), though wartwort, clearvers are had special efficacy, it also has the limitation of oneself.The medication to the jointing that at first is the short 2 leaf phases at wheat of medication phase.Secondly to the part succession crop dangerous as: the safety interval of back stubble plantation peanut is minimum to be four months.
Summary of the invention
The problem that the present invention need solve just is to overcome the defective of prior art, and a kind of wheat paddock weed killer herbicide is provided, and it can both effectively be prevented and kill off the common weeds of wheat paddock and for difficult weeds wartwort, clearvers with control special efficacy be arranged.
For addressing the above problem, the present invention adopts following technical scheme:
Wheat paddock weed killer herbicide of the present invention, it contains the thifensulfuronmethyl of 1 part-99 parts (wt) and the fluroxypyr (ester) of 1 part-99 parts (wt), and contains optional carrier, surfactant, dispersant and/or agricultural adjuvant.
Preferably, the present invention contains the thifensulfuronmethyl of 1 part-30 parts (wt) and the fluroxypyr (ester) of 10 parts-30 parts (wt).
More preferably, the present invention contains the thifensulfuronmethyl of 15 parts (wt) and the fluroxypyr (ester) of 20 parts (wt).
More preferably, the present invention is multiple formulations such as the missible oil that is mixed with by thifensulfuronmethyl and fluroxypyr (ester) and corresponding adjuvants, wetting powder, water dispersant, dry suspending agent.
Thifensulfuronmethyl is a selective herbicide behind the seedling, can be by stem leaves of plants, and root system absorbs, and conduction rapidly.By the leucic biosynthesis of inhibition side chain amino acid, and stop cell division, sensitive plant is stopped growing, dead in 1 to 3 week after being subjected to medicine.This medicament can be decomposed by soil organisms rapidly in soil, after 30 days succession crop is not had poisoning.Applicable crops: wheat, corn, soybean etc., prevent and kill off object: can effectively prevent and kill off most of annual and perennial broadleaf weed, as: piemarker, wild garlic, Amaranthus retroflexus, shepherd's purse, lamb's-quarters, clearvers, kitchen garden, salsola collina, black nightshade, ox chickweed, chickweed, the seed of cowherb, Veronica, summer cypress, Ben Shi knotweed, red shank etc.
Making its grand weed killer herbicide is a kind of efficient broadleaf weed herbicide that the farming of LG-DOW benefit aims at the wheat development and production, and its active ingredient is fluroxypyr (ester), and special efficacy is prevented and kill off clearvers, chickweed, descurainia sophia (l.) webb ex prantl, wartwort etc.
The present invention is composite with both, to the common weeds of wheat paddock can both effectively prevent and kill off and for difficult with the control weeds wartwort, clearvers special efficacy is arranged.Crop for back stubble plantation peanut, vegetables is safer, and its safety interval only needs 1 month.
Embodiment
