甲咪唑烟酸 - imazapic

一、除草机理

 

甲基咪草烟属内吸传导型选择性苗后除草剂。药剂主要通过茎、叶吸收,也能通过根吸收,通过抑制植物的乙酰乳酸合成酶,阻止支链氨基酸的生物合成,从而破坏蛋白质的合成,干扰DNA合成及细胞分裂与生长,最终造成植株死亡。

 

二、防除对象

 

主要用于花生田早期苗后防除一年生单、双子叶杂草及部分多年生杂草,对莎草科杂草、稷属杂草、草决明、播娘蒿等具有很好的活性。

 

三、使用技术

 

在花生2-4片羽状复叶期,每亩用24%水剂20~30毫升,对水40千克,均匀喷雾。

 

四、注意事项

 

1.该药持效期较长,施药剂量不能过高,施药期也不宜过晚,否则会对小麦产生药害。

 

2.施药剂量偏高,施药后如遇高温干旱,特别是沙土地花生会发生一定的药害,施用时务必注意。

Herbicidal mechanism

 

Methyl imidazolam is an endogenous and selective herbicide. Drugs are absorbed mainly through stems and leaves, but also through roots. They inhibit the biosynthesis of branched-chain amino acids by inhibiting plant acetolactate synthase, thereby destroying protein synthesis, interfering with DNA synthesis, cell division and growth, and ultimately causing plant death.

 

Two, object prevention

 

It is mainly used to control annual monocotyledon and dicotyledon weeds and some perennial weeds after early seedling in peanut field. It has very good activity to Cyperaceae weeds, millet weeds, cassia seed and Artemisia sophia.

 

Three, the use of Technology

 

At the 2-4 pinnate compound leaf stage of peanut, spray evenly with 24% water 20-30 ml per mu and 40 kg water.

 

Four, matters needing attention

 

1. The duration of the drug is longer, the dosage of the drug should not be too high, and the period of application should not be too late, otherwise it will cause harm to wheat.

 

2. The dosage of pesticide is on the high side. If the pesticide is applied after high temperature and drought, especially peanut in sandy land will occur certain pesticide damage.
