Characteristics of nicotinyl atrazine

Nicosine atrazine is a selective herbicide before and after seedling. The root absorbs mainly, but the stem and leaf absorb little. The herbicidal effect and selectivity are the same as simazine, which is easy to be leached to the deeper soil by Rain Water, and is also effective for some deep-rooted grasses, but it is easy to cause drug damage. The duration of effect is also longer.

I. scope of application

It has a wide herbicide spectrum and can control a variety of annual Gramineae and broad-leaved weeds. It is suitable for dry field crops such as corn, sorghum, sugarcane, fruit trees, nursery, woodland, etc., to control Tripterygium, barnyard grass, dogweed, sedge, sorghum, polygonum, quinoa, cruciferae, legume weeds, especially for corn (because of the detoxification mechanism in corn), and also has a certain inhibitory effect on some perennial weeds.

II. Usage

1. The use of summer corn before emergence after sowing, the quality of soil organic matter is 1% 2% in North China and Shandong, 150-200 grams of 50% wettable powder per mu, or 175-200 ml of 40% suspending agent per mu; the northeast region with soil organic matter content more than 3% of 6%, 200-250 grams of 50% wettable powder per mu, or 200-250 grams of 40% suspending agent, the lower limit of sandy soil and the upper limit of clayey soil. 1-3 days after sowing, evenly spray 30 kg of water on the soil surface. After the emergence of maize seedlings, the suitable period is maize 4-leaf stage, weeds 2-3 leaf stage; sandy soil with low organic matter content, use 50% wettable powder or 40% suspending agent 200-250 grams per mu. Spray 30-50 kg of water. Spring corn use 40% suspending agent 200-250 ml per mu, add 30-50 kg of water, spray soil surface before sowing, mix soil after spring drought medicine, or appropriate irrigation. Or do stem and leaf treatment in the 4-leaf stage of maize. In order to reduce or eliminate the drug damage of atrazine to wheat in the continuous cropping area of corn and winter wheat, atrazine can be mixed with Caojingjin, Rasol, Duer, 2myryl D butyl ester, accompany dinong and chlorotoluron herbicides.

two。 5-7 days after the sugarcane was planted in the sugarcane field, the weeds were partially unearthed, using 50% wettable powder or 40% suspending agent 200-250 grams per mu, adding 30 kg of water, and spraying evenly on the surface.

3. Tea gardens, orchards and vineyards use the peak period of weed germination in the fields from April to May, first eradicate the unearthed weeds and overwintering miscellaneous scratches, and then evenly spray the soil surface with 40% suspending agent 250-300 grams per mu and 40 kg of water.

Nicosine atrazine in spraying, should be careful not to re-spray, it is best to finish spraying, the most suitable time is before 9: 00 in the morning and after 5: 00 in the afternoon. Pay attention to protection so as not to touch or inhale.
