Generally, after process, weeds stop growing immediately, the leaf chlorisis newly sent after absorbing 4-5 days, the worst
Dead and to spread to 20-30 days weeds of whole plant the most withered.This medicament can be absorbed by weeds stem and leaf, can suppress again in soil
Suppressing weed seed germination, controls the time longer, and the lasting period is about more than 40 days in spring and summer, and autumn and winter is more than 120 days.
Flazasulfuron is the herbicides special that first, China is formally registered on warm-season turf (Korea lawn grass class and Bermuda grass class).
Medicament can be decomposed, be converted into innocuous substance rapidly after contacting medicament with Bermuda grass class turfgrass by Korea lawn grass, does not interferes with lawn
Normal growth is high to turfgrass safety.Use at lawn rest period, do not interfere with germination in the future and growth.Extensively application
In greening lawn, golf course etc..
Fluroxypyr (Fluroxypyr), is the pyridine oxycarboxylic acid class herbicide developed by Dow Chemical Co., chemical name:
4-amino-3, the chloro-6-of 5-bis-fluoro-2-pyridine fluoroacetic acid, its structural formula is as follows:
Pyridine fluoroacetic acid class herbicide.Having Uptake and translocation effect, be quickly absorbed by plants after medicine, sensitive crop occurs that typical case swashs
The reaction of element class herbicide, plant deformity, distortion.Temperature without impact on the final effect of its weeding, but affects its drug effect and plays
Speed.Typically when temperature is low, drug effect plays slowly, stops growing after can making dunsiekte, but the most dead, temperature liter
After height, plant is the most dead.Use optimum period wider, can be used for Semen Tritici aestivi, Fructus Hordei Vulgaris, Semen Maydis, Fructus Vitis viniferae and orchard, pasture, forest farm etc.
