Amide selectivity contact kill herbicide, is mainly used for
seedling or direct seeding paddy field, is the specific medicine
for controlling barnyardgrass, can also be used to control a
variety of other grasses and dicotyledonous weeds, such as duck
tongue grass, cress, Digitaria Sanguinalis, Setaria viridis,.
Propanil in plants almost not only in drug contact parts
transporting, play a role. Its mechanism is various, not only the
destruction of plant photosynthesis, but also the inhibition of
respiration and the role of oxygen in the role of phosphorylation,
interfering with the synthesis of nucleic acids and proteins, etc..
So that the physiological function of sensitive plants affected by
accelerated leaf dehydration, gradually withered, finally died. Due
to propanil in rice plants was hydrolase quickly degrade into
non-toxic substances due to the degradation ability of rice to
propanil was 20 times greater than barnyard grass, so the safety of
rice. When using general in barnyard grass of the second leaf to
leaf heart period, with 20% of propanil EC 113 ~ 150mL/100m2, of
water 5.3kg do stem and leaf spraying processing. Spraying should
be arranged on the eve of dry water, second days after spraying dew
dry, then every 24h irrigation, maintain normal irrigation and
drainage 2D. Light intensity, better effect. The temperature is
above 30 DEG C, easy to produce injury.
