Abstract
Fluroxypyr cyhalofop-butyl complex weedicide belongs to technical field of pesticide.Its objective is provides a kind of and can prevent and kill off the paddy field grassy weed, can prevent and kill off broad leaved weed again, and succession crop is not had influence, the fluroxypyr cyhalofop-butyl complex weedicide of environmentally friendly and price economy again.Its technical essential is: it is made by the raw material and the auxiliary material of following quality percentage composition: fluroxypyr 15-60, cyhalofop-butyl 5-20, cosolvent 2-15, surfactant 5-15, solvent complements to 100.It is to rice safety, and 90g/ mu can reach good herbicidal effect in the paddy field, and the preventive effect of weeds can reach more than 80% in 30 days, reached more than 90% in 60 days, and along with the increase of dosage, preventive effect obviously strengthens; A dispenser can be prevented and kill off the weeds in the crop whole growing, and second stubble crop is not had influence.Be used to prevent and treat the rice field crop smothering.
Description
Technical field:
The present invention relates to a kind of fluroxypyr cyhalofop-butyl complex weedicide, be used to prevent and treat the rice field crop smothering, belong to technical field of pesticide.
Background technology:
Paddy rice is one of China staple crops, continuous expansion along with its cultivated area, the rice field crop smothering also day by day increases in the production that constantly enlarges, endanger also serious day by day, wherein paddy field field crop smothering area accounts for more than 25% of total cultivated area, wherein serious injured area is more than 7%, and the general underproduction is more than 13%, when serious even total crop failure.Can therefore, effectively control the crop smothering in the paddy rice, the high yield of stabilization of rice also just becomes one of major subjects of modern agricultural herbicide research.
At present, in the various herbicides for use in paddy on the market, cyhalofop-butyl (cyhalofop-butyl) is an inner sucting conduction type virtue phenoxy propionic acid class weed killer herbicide, absorb phloem conduction, the meristematic tissue of accumulation and plant by plant leaf blade or leaf sheath, suppress acetyl-CoA carboxylase, fatty acid is synthesized stop, the meristematic capacity forfeiture of plant causes plant death at last.Though it can better prevention paddy field crop smothering, it is too high that its maximum defective is to prevent and treat cost, and a mu control cost surpasses 20 yuan, and is then higher for above the average age for marriage crop smothering cost, and mu control cost is above 45 yuan.Thereby also be difficult to be accepted by numerous medicinal herb growers.
Summary of the invention:
The object of the present invention is to provide and a kind ofly can prevent and kill off the paddy field grassy weed, can prevent and kill off broad leaved weed again, and succession crop is not had influence, the fluroxypyr cyhalofop-butyl complex weedicide of environmentally friendly and price economy again.
Its technical scheme is: a kind of fluroxypyr cyhalofop-butyl complex weedicide, it is characterized in that: it is made by the raw material and the auxiliary material of following quality percentage composition: fluroxypyr 15-60, cyhalofop-butyl 5-20, cosolvent 2-15, surfactant 5-15, solvent complements to 100.
Above-mentioned solvent is one or both in toluene, dimethylbenzene, solvent naphtha or the benzene monomer; Cosolvent is one or more combinations in methyl alcohol, ethanol, cyclohexanone, dimethyl formamide, the dimethyl sulfoxide (DMSO); Surfactant is one or more combinations in NNO, BX, LS, lignosulfonates, carboxymethyl cellulose, alkylsulfonate, fatty alcohol sulfonate, alkylphenol polyoxyethylene, dodecyl sodium sulfate, lauryl sodium sulfate, farming breast 2201, farming breast 8316, farming breast 8209, farming breast 8210, agricultural newborn 500# or the farming breast 8220.
Solvent, cosolvent are dropped into the back that stirs in the still drop into fluroxypyr, drop into cyhalofop-butyl again after the dissolving fully, both got 25% fluroxypyr cyhalofop-butyl missible oil after stirring.
Its technique effect is: fluroxypyr cyhalofop-butyl complex weedicide of the present invention, show by field efficacy, in the paddy rice 2-4 leaf phase, weeds 1-6 leaf does not wait the phase, utilize the effective equivalent 70,80,90,100 of weed killer herbicide of the present invention, 110g/ mu, convert water 40kg/ mu and spray 30,60 days preventive effect such as following table:
By range estimation, paddy rice does not see symptom of chemical damage from the dispenser to the maturing stage, to rice safety.90g/ mu can reach good herbicidal effect in the paddy field, and the preventive effect of weeds can reach more than 80% in 30 days, reached more than 90% in 60 days, and along with the increase of dosage, preventive effect obviously strengthens; A dispenser can be prevented and kill off the weeds in the crop whole growing, and second stubble crop is not had influence, and environmentally friendly, is present complex weedicide satisfactory for result.Be used to prevent and treat the rice field crop smothering.
Embodiment:
Embodiment 1 drops into dimethylbenzene 52kg, dimethyl sulfoxide (DMSO) (DMSO) 8kg, methyl alcohol 5kg earlier in still, back input fluroxypyr 20kg stirs, dissolve back input cyhalofop-butyl 5kg fully, the agricultural breast 8316 of 10kg is dropped in the back that stirs, and has both got 25% fluroxypyr cyhalofop-butyl missible oil.
Embodiment 2 drops into dimethylbenzene 50kg, dimethyl sulfoxide (DMSO) (DMSO) 10kg, methyl alcohol 5kg earlier in still, back input fluroxypyr 15kg stirs, dissolve back input cyhalofop-butyl 10kg fully, the agricultural breast 8316 of 10kg is dropped in the back that stirs, and has both got 25% fluroxypyr cyhalofop-butyl missible oil.
