Base) methyl] benzoyl]-hydroresorcinol.Ring sulphur ketone is three ketones corn field herbicide, and its activity of weeding passes through 4- hydroxyls
Base phenylacetone vinegar dual oxide enzyme (HPPD) inhibitor is showed, after HPPD is suppressed, junket ammonia in weeds separate living tissue
Acid accumulation and plastoquinone lack, and after 3-5 days, yellow symptom occur in weeds, finally spread to whole strain, and weeds albefaction is dead.Ring sulphur
Ketone is mainly used in preventing and kill off corn field and a variety of grassy weeds of paddy Tanaka and broad leaved weed, to Cirsium, japanese bearbind genus, Veronica
A variety of weeds such as category, smallflower galinsoga herb category, Urtica, yellow chamomile and clearvers, which also have, very strong kills effect, moreover it is possible to kill to grass
Sweet phosphine, Mediben and ALS inhibitor classes herbicide produce the weeds of resistance.In addition, ring sulphur ketone has stronger anti-rainwater to wash away energy
Power, and good activity of weeding can be kept in crop whole growth period without being caused harm to next batch of crop.
Cyhalofop-butyl (cyhalofop-butyl), belongs to aryloxyphenoxypropionic class herbicide.Rice terrace selective herbicidal
Agent, can only make cauline leaf process, and bud pre-treatment is invalid, mainly prevent and kill off barnyard grass, the grassy weed such as moleplant seed.Uptake and translocation weeding
Agent.Absorbed by the blade and leaf sheath of plant, bast conduction accumulates the meristem zone in plant, resists acetyl coenzyme A
Carboxylase (ACCase), makes aliphatic acid synthesis stopping, and the growth division of cell can not be normally carried out, and the structure containing fat such as membranous system is broken
It is bad, finally result in Plant death.Weeds Mortality Ratio is absorbed into from cyhalofop-butyl slower, generally require 1-3 weeks.Weeds exist
Symptom after dispenser is as follows：The tender shoots atrophy of four leaf stage, causes death.The old leaf of two leaf stage is changed very little, and keeps green.In water
In rice body, cyhalofop-butyl can be degraded quickly as to two inactive acid-state of acetyl-CoA carboxylase, thus has height to paddy rice
