一、玉米田施药时做到:要分清品种,不要盲目用药由于现在的玉米苗后除草剂大多是烟嘧磺隆成分,一些玉米品种对该成分敏感,易发生药害。有的产品注明禁止在玉米自交系、甜玉米、糯玉米等品种上使用,因此,苗后除草剂不是什么样的品种都能使用,应详细阅读产品的各项说明,能用则用,不当用则不用,防止玉米苗产生药害。 First, the corn field to do: to distinguish between varieties, do not blindly use the drug Because most of the corn seedling herbicide is nicosulfuron composition, some corn varieties sensitive to the composition, prone to injury. Some products indicate that it is forbidden to use on maize inbred lines, sweet corn, waxy corn and other varieties. Therefore, post-emergence herbicides can not be used in any varieties. They should be read in detail and can be used Improper use is not necessary to prevent corn seedling injury.
