精噁唑禾草灵是一种除草活性很高的芳氧酸酯类内吸传导型苗后茎叶处理剂。对冬小麦和春小麦都很安全。能有效防除小麦田野燕麦、看麦娘、日本看麦娘、硬草、黑麦草、菵草等多种禾本科杂草,对雀麦等防效较差,对阔叶杂草无效。在小麦2~4叶期,杂草3叶期前,每亩用6.9%精噁唑禾草灵水乳剂50~70毫升或10%精噁唑禾草灵乳油30~50毫升,对水30~40千克喷雾。该药施用时应尽量早用,杂草分蘖后耐药性增强,防效较差,所以年后春防用药要适当增加用量。用药时遇低温,小麦叶片会轻微发黄,以后随其生长恢复正常。
Fenoxaprop grass is a highly herbicidal activity of the aryloxyacid-type conduction shoots stems and leaves treatment agent. It is safe for both winter wheat and spring wheat. Can effectively control the wheat field oats, see Ophiopogon japonicus, Ophiopogon japonicus, hard grass, ryegrass, razorgrass and other grass weeds, such as the control effect on the poor brittle, the broad-leaved weeds is invalid. In wheat 2 to 4 leaf stage, weeds before the 3-leaf period, with 6.9% fenoxaprop-50% emulsifiable concentrate emulsions 50ml or 10% fenoxaprop EC cream 30 ~ 50ml, water 30 ~ 40 kg spray. The drug should be used as early as possible, weeds after tillering enhanced resistance is poor, so after the spring anti-drug dosage should be appropriate to increase. When treated with low temperature, wheat leaves will be slightly yellow, with its growth returned to normal.
