How to use paclobutrazol in vegetable production
Paclobutrazol is a plant growth regulator and fungicide newly developed by the British Imperial (ICI) Chemical Corporation in the late 1970s. It is a plant growth retardant, also known as an inhibitor. Paclobutrazol is a highly effective and low-toxic plant growth retardant that can increase the content of chlorophyll, protein and nucleic acid in plants, reduce the content of gibberellin and indole acetic acid, increase the release of ethylene, and increase lodging resistance, drought resistance, and cold resistance. And resistance to disease and other stress resistance, increase production, improve quality and increase economic efficiency. It has received widespread attention and is considered to be one of the best growth retardants to date. The response of vegetables to paclobutrazol is relatively sensitive, and the use concentration should be different according to the weather, crop types, different growth periods, and different concentrations. Our experience shows that the use of low concentrations within the effective range; spraying as long as the plant stems and leaves to be wet, but not for the degree of drip, not heavy spray; can be sprayed as far as possible foliar spray, not land, In order to avoid adverse effects on the soil in the post-season crops, it is generally only sprayed once. In order to facilitate the rational use of paclobutrazol by farmers, combined with our practical experience in recent years, collect and collate relevant information for your reference.
1, root vegetables
