Atrazine 80% WP, 50% SC Agricultural Herbicides for weeds in the corn field Triazobenzene herbicides

Mode and mechanism of actionSelective uptake of herbicide before and after seedlings. Atrazine is the main source of root absorption in the plant. The absorption of stem and leaf is slightly less, through the xylem to the meristem and leaf, interfering with photosynthesis and causing the weeds to die. In maize and other resistant plants, benzoxazine was hydrolysated into a non-toxic hydroxyl three nitrogen benzene and was selected.Prevention and control objectThe annual gramineous weeds and broadleaf weeds such as malt, barnyard grass, barnyard grass, sedge, sedge, see Mai Niang, Polygonum and Chenopodium, also have certain inhibitory effects on some perennial weeds.Matters of meaningSoybean, peach, wheat and rice are sensitive to atrazine and should not be used. When the corn field is wheat and rice, the dosage should be mixed with other safe herbicides. Soil with more than 6% organic matter is not suitable for soil treatment. Stem and leaf treatment is good.(1) the residual effect period of atrazine is longer, and some of the later crop sensitive crops, such as wheat, soybean and rice, can be mixed with other herbicides, or improve the technology to avoid the effect on the later crop. Most of the post-crop crops in Beijing and North China are winter wheat, so atrazine alone can not exceed 3kg/hm2 (commercial volume) (effective component 1.5kg). Uniform spray is required. Otherwise, excessive dosage or uneven spray will often cause damage to wheat spots and even death. The amount of corn in the field can be improved properly. Forage corn is used only in Shanghai area before seeding. During the 3~4 leaf stage of seedling stage, stem and leaf treatment had an effect on the subsequent rice.(2) The use of atrazine in orchards is unsafe for peach trees, which are sensitive to atrazine, characterized by yellowish leaves, lack of green, fruiting and serious yield reduction.(3) it is not suitable for the use of atrazine in corn interplanting legumes.(4) when the soil is treated with atrazine, the soil surface should be leveled before the application of the soil surface.(5) Atrazine is a low toxic herbicide, but dispensing and applying personnel still need to pay attention to prevent contamination of hands, face and skin, if contaminated should be immediately cleaned. Atrazine can cause poisoning through the esophagus and respiratory tract, poisoning and rescue no specific antidote.(6) after the application of medicine, all kinds of tools should be carefully cleaned, sewage and residual liquid should be properly handled or preserved, and they should not be dumped at any time so as to avoid pollution of water, soil and drug damage. Empty bottles should be recovered in time and handled properly. No longer be used for them.(7) attention should be paid to light lifting when handling, so as to avoid damage and pollute the environment. There should be special wagons and warehouses for transportation and storage, and not for transportation with food and daily necessities. It should be stored in a dry and well ventilated warehouse.
