麦极在小麦田的应用效果及施药器械对其药效的影响

Effect of Clodinafop-propargyl on Gramineous Weeds in Wheat Field and Influence of Atomizers on Its Efficacy

冬前杂草幼苗或者冬后小麦返青期使用麦极16g/667m2可有效防治小麦田看麦娘、菵草、硬草等禾本科杂草,相同使用剂量下,使用超低容量的弥雾法施药可适当提高其药效。

Clodinafop-propargyl was effective on gramineous weeds, such as Alopecurus aequalis Sobol,, Beckmannia syzigachne （Steud.） Femald, sclerochloa kengiana （Ohwi） Tzvel. and so on, while it was applied in wheat field at weed seeding stage or return-green stage of wheat, under the dosage of 16g/667m^2 or above. The method of ULV spraying by mist spraver could increased its efficacy moderately.
