| Overview | Alanic acid-S-methyl also known as Activated ester (1,2, 3-benzothiadiazole-7-thiocarboxylic acid methyl ester), which is a plant disease resistance activator. It itself has no bactericidal activity and therapeutic effect, but it is absorbed by the plant to activate the plant resistance mechanism, so that the plant to a variety of fungi, bacteria, nematodes, and Virus produce a broad spectrum of self-protection and produce durable resistance. |
| toxicity | rat acute oral LD50>2000mg/kg, rat acute percutaneous LD50>2000mg/kg, rats with acute inhalation LC50>5000mg/L (4H). There was no irritation to rabbit eyes and skin. No teratogenic, carcinogenic or mutagenic effects were observed in animal experiments. Rainbow trout lc500.4 mg/L (96H), big Turus lc502.8 mg/L (96H), Daphnia ld502.4 mg/L (48h), wild duck ld505200 mg/kg (8h). |
| Use | benzothiadiazole carboxylic acid ester fungicide, but no bactericidal effect, belonging to plant disease resistance activator. A variety of biological and non-biological factors can stimulate the defense response of the plant itself, that is, "systemic active resistance", so that the plant has a self-protective effect on a variety of fungi and bacteria. Suitable for rice, wheat, vegetables, bananas, tobacco and other crop protection agents used to control powdery mildew, rust, downy mildew. Foliar application of 30g active ingredient/hm2 on cereal crops can effectively prevent powdery mildew, and the residual period can last for 10 weeks. And can prevent leaf blight and rust. The use of 12g/hm2 every 14 days can effectively prevent tobacco downy mildew. With other conventional medicaments metalaxyl, mancozeb, enoyl-baroline mixed, not only can improve the control effect of Activated ester, but also can expand the scope of disease prevention. |
