Jan 02,2024
(1) Weeds control in wheat field: during the post winter green returning period of winter wheat or the period from the peak tillering stage to the early jointing stage, the 3-5 leaf stage of spring wheat, and the 2-4 leaf stage of broadleaf weeds, 50-66.7 ml of 20% isofluropyranoxyacetic acid emulsifiable concentrate shall be used per mu to spray water.
(2) Weeds control in corn field: before the post six leaf stage of corn seedlings and the 2-5 leaf stage of weeds, 50-66.7 ml of 20% isofluropyranoxyacetic acid emulsifiable concentrate per mu is used to spray water; To prevent and control difficult to control weeds such as convolvulus, small convolvulus, and purslane, use 66.7-100 milliliters of 20% chloropyranoxyacetic acid isooctyl EC per acre.
(3) Prevention and control of weeds in grapes, orchards, non cultivated land and rice ridges: during the 2-5 leaf stage of weeds, 75-150 ml of 20% isofluropyroxyacetic acid isooctyl emulsifiable concentrate per mu is used to spray water. To prevent and control the occurrence of hollow lotus seeds and vegetables in rice fields, 50 milliliters of 20% chlorofluoropyranoxyacetic acid isooctyl emulsifiable concentrate, or 20 milliliters of 20% chloropyranoxyacetic acid isooctyl emulsifiable concentrate mixed with 200 milliliters of 41% manganese water solution, or 30 milliliters of 20% chloropyranoxyacetic acid isooctyl emulsifiable concentrate mixed with 150 milliliters of 41% manganese water solution should be used per acre. To prevent and control difficult to control weeds such as Scirpus mariqueter, Charcoal mother grass, Raspberry, Commelina communis, Acorus calamus, etc., mix 80 to 100 milliliters of 20% Chlorofluoropyranoxyacetic Isooctyl EC with 100 to 150 milliliters of 41% Manganese water solution per acre.
2. Mixed use.
When mixed with other herbicides, the herbicide spectrum can be expanded and costs can be reduced. In wheat fields, 30 to 40 milliliters of 20% chlorofluoropyranoxyacetic acid isooctyl ester emulsifiable concentrate and 35 milliliters of 72% 2,4-butyl ester emulsifiable concentrate or 150 milliliters of 20% dimethyltetrachloro water solution can effectively control weeds such as Veronica, Zeqi, Shepherd's purse, crushed rice shepherd's purse, pistillary mustard, quinoa, Quercus, Sonchus coriaceae, Convolvulus officinalis, Scirpus, Xanthium sibiricum, and Abutilon; Using 50 to 66.7 milliliters of 20% chlorofluoropyranoxyacetic acid isooctyl ester emulsifiable concentrate and 50 to 67 milliliters of 6.9% Puma water emulsion per acre can effectively control weeds in the grass family, such as wild oats, Kanmai Niang, hard grass, Bangtou Grass, barnyard grass, horse Tang, and Qianjinzi.
