百菌清又名打克尼尔(Daconil),TPN,Forturf,DAC—2787,化学名称是2,4,5,6—四氯—1,3,苯二甲腈。在常温下稳定,在碱性或酸性溶液中稳定,对紫外光稳定。毒性低,对小白鼠口服致死中量为3.7克/公斤。百菌清对果树、蔬菜的多种真菌病害有良好的防治效果,耐雨冲刷,持效期长,效果稳定,对人畜毒性低。 1974年我省各地对日本进口的75％百菌清(打克尼尔)进行了花生锈病的盆栽药效、持效、大田小区及大田生产试验,结果防锈效果显著。
Chlorothalonil, also known as Daconil, TPN, Forturf, DAC-2787, has the chemical name 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile. Stable at room temperature, stable in alkaline or acidic solution, stable to UV light. Low toxicity, oral mice lethal in the amount of 3.7 g / kg. Chlorothalonil on fruit trees, vegetables, a variety of fungal diseases have a good control effect, resistance to erosion, persistence period, the effect is stable, low toxicity to humans and animals. In 1974, 75% of chlorothalonil (Kocirin) imported from Japan was used in potted plants of peanut rust for efficacy, persistence, field plot and field test in 1974 in our province. As a result, the anti-rust effect was remarkable.
