Atrazine is also known as Atrazine. The main dosage forms are: 50%, 80% WP, 38%, 40% SC, 4%, 8%, 20% granules, etc. It is a selective pre-emergence, post-emergence herbicide. Control of annual broadleaf weeds and grass weeds, control broadleaf weeds better than grass weeds, and also have a certain inhibitory effect on perennial weeds. Before weed germination or post-emergence 1-3 leaf stage, use 38% of decaned water SC200-250 ml per acre. Due to its long-lasting effect, it is generally used in combination with other herbicides to reduce the amount of production and reduce the occurrence of phytotoxicity.
Atrazine's killing spectrum and control effect:
Outstanding effect (more than 90%) weeds, anti-branches, cockroaches, purslane, ramie, cockroaches, goosegrass, foxtail effect (70-90%) weeds, crabgrass, barley, barley, Solanum nigrum Poor ear effect (50-70%) weed iron sputum effect is very poor (less than 50%) or ineffective weeds morning glory, field convolvulus, fragrant aconite but atrazine is a long-acting pre-emergence herbicide The half-life in soil is 35~50 days. The soil of clay soil has strong adsorption to the drug, and the residual time is longer. It often causes phytotoxicity to some crops, except for the northeast, which can be used alone. Generally used in combination. It has been reported that different types of maize varieties have different resistance to atrazine, and this drug cannot be used in corn inbred lines, sweet corn, waxy corn, popcorn field and corn field. It is best not to use this medicine in sweet corn fields to avoid phytotoxicity.
After the application of atrazine in the northeastern region such as Heilongjiang, the soybean growth will be severely inhibited or the dead seedlings will be produced, resulting in a significant reduction in production. If the corn field is used in the northeast region, atrazine + acetochlor (isomethasamine, metolachlor) + 2,4-diisooctyl ester, less than 1710 grams per year (active ingredient) / In the hectares, the sorghum can be carefully planted with spring soybeans; the amount used in the next year is 1710~2400g (active ingredient)/ha, and after the spring soybeans meet the rainfall and the sun is full after the rain, the phytotoxicity is serious, the yield reduction is obvious, and the cultivation is not recommended. Spring soybeans can be planted with silage corn, fresh corn, sorghum, hazelnuts, etc.; the amount used in the past year is higher than 2400 grams (active ingredient), and the rear can only grow silage corn, fresh corn or popcorn.
In the Huanghuai region, corn and wheat rotation, when the corn acre using the active ingredient of atrazine is more than 80 grams, it is easy to cause low wheat emergence rate or inhibit seedling growth. Corn, rice rotation, when the corn acre with the active ingredient of atrazine exceeds 70 grams, it is easy to cause phytotoxicity to the sorghum rice.
Sweet corn is a large-scale crop that has been widely planted in South China in recent years. Due to the special climatic conditions in Guangdong, 2-3 一年 can be planted a year. Therefore, the herbicide, atrazine, which is safe for sweet corn, is frequently used, thus causing soil pollution. In the south, sweet corn and sticky corn are used in atrazine. When the green tea is harvested, the cruciferous vegetables and legumes are planted, which often causes chlorosis, leaf curl and plant dwarf. In the case of corn fields intercropped with beans, atrazine cannot be used.
When using atrazine, when the liquid is drifted due to improper use of the wind or the method, it may cause yellowing of the leaves or curling of the leaves of adjacent watermelons, cucumbers, beans, peach trees, poplars, jujubes, etc. Phenomenon, when severe, leaves will fall off. Crops such as wheat, rice, spinach, cucumber, watermelon, tomato, cabbage, cauliflower, kale and canola are very sensitive to atrazine. In the soil, when the amount of atrazine remaining in the soil exceeds 0.080 mg, the growth of Chinese cabbage is obviously inhibited; when it exceeds 0.104 mg, the growth of cabbage is abnormal; when it exceeds 0.081 mg, the growth of indica rice is abnormal. That is to say, when there is even a little bit of atrazine remaining in the soil, the growth of the above-mentioned atrazine-sensitive crops will be problematic.
Some scholars have divided the resistance of atrazine to crops or vegetables into four categories:
Highly resistant crops: corn, sorghum, sugar cane;
Moderately resistant crops: sunflower, celery, kale, tobacco;
Weakly resistant crops: pepper, wheat, soybean, flax, oatmeal;
Very weak resistant crops: cucumber, watermelon, peach, millet, rice.
According to the actual situation in the locality, pay attention and attention when changing and applying Atrazine to reduce or avoid unnecessary losses. The industry has a common understanding that environmental pollution can be caused to groundwater or surrounding water sources due to the application of runoff or leaching after the trip to Tianjin. There are also many negative reports on the torazine in Europe and the United States. It has been pointed out that due to the pollution of water sources, it has a great impact on the reproduction of frogs, and there are reports that affect people's health.
How to avoid the residual troubles of Atrazine?
1. Deeply turn the soil, first use the deep plough to turn it over, and strive to turn the residual components of atrazine in the topsoil below;
2. Adding biological fertilizer and fermented farmyard manure to accelerate the decomposition of residual atrazine. Rotating 2~3 times of soil after application;
3, first planting sorghum or transplanting fruit trees, but when planting fruit trees, roots should be used to treat roots to accelerate the growth of new roots;
4, combined with soil disinfection, prevention of soil-borne root diseases, it has been found that the use of ground can be used to treat soil, can also reduce the residual phytotoxicity of atrazine;
5. The use of ammonium nitrogen fertilizer can also reduce the harm of atrazine to crops. (Pesticide Market Information)
