| 摘 要： | 250g/L吡唑醚菌酯乳油是新一代高效杀菌剂,为在玉米上安全使用该药剂,于2009年进行250g/L吡唑醚菌酯乳油对玉米(甜玉米)营养生长期的安全性评价试验。试验结果表明,250g/L吡唑醚菌酯乳油3000倍、2000倍和1000倍在玉米营养生长期进行喷药处理,植株未见药害现象,玉米茎杆和嫩叶生长正常,而750倍、500和250倍喷药后,发现玉米个别嫩叶基部有轻微或轻度的药害现象,但数天后可缓解,不影响玉米中后期的正常生长及开花结果。试验结果可知,250g/L吡唑醚菌酯乳油防治玉米病害的使用浓度以1000～3000倍为宜。

| Abstract: | 250 g/L Pyraclostrobin EC was a new type fungicide,it was evaluated the safety on corn during the vegetative growth in 2009. Field tests showed that after spraying one time during the corn vegetative growth, 250 g/L Pyraclostrobin EC 3 000, 2 000 times and 1000 times treatments were safe to the vegetative growth stage of corn,and non-injury. However, 750, 500 and 250 times of the high concentration treatments during the vegetative growth of corn produced mild or light injuries, but they did not affect the n... |
