chemical name: 2-chloro-4-diethyl amine-6-isopropylamine-1,3, 5-triazine; the appearance is white powder, melting point is 173-175 ℃, the vapor pressure is 40μPa at 20 ℃. The solubility is 33mg/L in water, 28 g/L in chloroform, 28 g/L in acetone, 24g/L in ethyl acetate and 15 g/L in methanol. It is stable in slightly acidic or alkaline medium, but can be hydrolysis under high temperature.

It is endoscopic selective pre-seedling and post-seedling closure herbicide, dominantly absorbed by root, seldom by stem and leaf. Its mechanism and selective are similar to simazin, which can easily be washed by rain into the deeper soil and keep effective on some kinds of deep root grass. Meanwhile, the long duration of validity may prone to herbicide phytotoxicity. It has a wide range of herbicide spectrum, which can be used to eliminate a variety of annual gramineous and broad-leaved weeds. It is suitable for corn, sorghum, sugarcane, fruit tree, nursery, forest land and etc. dry field crops for controlling digitaria, barnyard grass, Setaria viridis, Sedge, Alopecurus, knotweed, pigweed, Cruciferae, Leguminosae weed. Especially for maize, it has good selectivity (internal detoxification mechanism of the plant), and also has certain effect on inhibiting some perennial weeds.

Attentions:

① In corn field, this product can be mixed with acetochlor for better efficiency, but it is not recommended to be mixed with other products.

② The dosage should base on soil, organic content, weed species, weeds density. Appropriately increasing dosage on acid soil, high organic content and weed density plot, but reducing usage in sandy, saline-alkali   and low organic content soil. 

③Users should apply this product in good soil condition like before, during or after rain to improve the effect of weeding. Low temperature below 15 ℃, drought, strong wind will low pesticide effect. When this product is precipitated, stir well and then apply as usual.

④The residue period of this preparation is long, and it is easy to cause drug damage to legumes, wheat, cotton, rice, cruciferous vegetables and poplars and other root trees which should avoid application.

⑤Calculating accurate acreage is required, and uniform in dosage, no weight and no leakage. Better effect when timely filling the soil after application.

⑥Do not wash pesticide instrument in ponds or drains to prevent contamination of other crops.
