Imidazolinones Agricultural Herbicides imazethapyr 10% SL, 98% TC
selective weed killer
It can be used as a selective herbicide in soybean field before and
after sprouting. It can effectively control grasses weeds such as
amaranth, polygonum, abutilon, Solanum nigrum, Xanthium sibiricum,
sage and tangerine.
The imidazolinone herbicides, physicochemical properties,
preparation methods and applications of imidazolidinic acid were
edited by Ding Hong from Chemicalbook.
Imidazolidone herbicides are inhibitors of side chain amino acid
synthesis, which are applied before or after buds. Gramineous weeds
and some broad-leaved weeds in soybean and other leguminous fields
have excellent control effects, such as amaranth, polygonum,
quinoa, solanum, xanthium, barnyard grass, sage, horse tang,
millet, etc. It can be made into water agent. Spraying method:
spraying 1 000-2 000 ml 5% water at seedling stage (soybean true
leaf stage to 2 compound leaf stage, weed 1-4 leaf stage), spraying
450-600 kg water evenly. At the seedling stage (when soil moisture
is good), 1500-2250 ml 5% water agent per hectare was sprayed
evenly with 450-600 kg water.
Notes: uniform and thoughtful application, avoid repetitive
application, can only be applied once a year; avoid aerial
application; do not drift to sensitive crops; sensitive crops are
beet, cabbage, rape, watermelon, cucumber, potato, eggplant,
pepper, tomato, sorghum and so on, the above crops in the next year
Sugar beet can not be planted within three years; this preparation
is suitable for soybean production areas in Northeast China.
Matters needing attention
Do not store or mix in unlined stainless steel or aluminum
containers, corrosive; do not mix with strong oxidants. Avoid
contact with skin, eyes or dirty clothing; avoid inhaling liquid
mist. Once the medication touches the skin and eyes, wash them with
plenty of clear water. If you take it inadvertently, do not vomit
and send it to the hospital immediately.
