禾草克(Nc—302)是由日产化学工业株式会社研制的一种新型除草剂,化学名称2-[4-(6-氯-2-喹嗯啉基氧化)—苯氧基]—丙酸乙酯,通用名Quizalofop—ethyl。禾草克是一种内吸选择性除草剂,主要由植物叶片吸收,传导全株积累于分生组织。禾草克能选择性杀死禾本科杂草的机制在于破坏生长点,同时也可以破坏新叶的基部组织。施药后敏感杂草叶片褪绿、坏死,7～10天全株枯死。由于禾草克在植物体内传导能力很强,因而能杀死多年生杂草的根茎。经世界各地试验证实,禾草克适用于包括大豆、棉花、甜菜、油菜在内的60余种作物,
Grass (Nc-302) is a new herbicide developed by Nissan Chemical Industries, Ltd. under the chemical name of 2- [4- (6-chloro-2-quinolinyloxy) -phenoxy] Ethyl acetate, common name Quizalofop-ethyl. Grass grams grams of a selective absorption of herbicides, mainly absorbed by plant leaves, the whole plant conduction in the meristematic organization. The mechanism by which grass can selectively kill gramineous weeds is to undermine growth points and at the same time to ruin the base tissues of new leaves. After the application of sensitive weed leaves chlorotic, necrosis, 7 to 10 days whole plant died. Graminectin can kill the roots of perennial weeds because of its high conductivity in plants. Tests around the world confirmed that Wo Ke Ke applied to include more than 60 kinds of crops, including soybeans, cotton, sugar beet, rape,
