Chlorpyridine has a better persistence in the tissues of plants. After application to weeds, it is absorbed by the leaves or roots of the plant, moves up and down in the plant and is rapidly transmitted throughout the plant. Let 's take a look at the tips on the use of clopyralid as a rapeseed herbicide and how to avoid the chlorophyll-induced phytotoxicity: Grow lights Shenzhen Huangtai Photoelectric Co.,Ltd. , https://www.huangtailightstrip.com
The use of clopyral acid as a rapeseed herbicide chloropicolinic acid can be used in cabbage-type and cabbage-type rapeseed fields (cannot be used in mustard-type rapeseed fields, otherwise it is easy to cause phytotoxicity).

The pesticide and the herbicide have good complementarity in the herbicidal spectrum, and are often mixed with the herbicide.
Chloropyridine acid as a rapeseed herbicide needs attention to the phytotoxicity of clopyralidic acid in the rapeseed seedling stage to the bud stage is safe for rapeseed, must pay attention to the rapeseed after convulsions, do not apply, so as not to cause phytotoxicity. Longquan has a moderate shelf life in the soil and may have adverse effects on a variety of crops, but most of the crops will not be medicated 10 months after the application of Dragon.
