Use of ginger herbicide

The ginger field was stagnant after using the herbicide, and the plants were short, some of the leaves were yellow, necrotic spots, local dryness, slight shrinkage and bending of the stems, and poor root development, which had a great influence on the yield. Proper use of pesticides is essential.
Recommended medication 1. Before sowing: Spray with metolachlor or alachlor. 2. Pre-emergence seedlings: commonly used oxaloin, chlorpyrifos, herbicide ether, butachlor, and chlorpyrifos in the pre-emergence spray of ginger. Sand land use needs to be reduced. 3. After the seedling: chlorofluorophenoxyacetic acid directed spray.
Proper use of herbicides :
1. Master the amount and concentration of herbicides. When using the herbicide, the liquid should be sprayed evenly, and the walking speed, manual control of the width and width of the spray, and the speed should be uniform.
2. Pay attention to the sensitive period of crops.
3. Prohibition of chaos.
4. Herbicide use technical operation points (1) "One level": the ground should be flat. The field of application should be finely cultivated to ensure that the ground is flat, no large clods, no pits. (2) "Two uniforms": the medicine should be evenly mixed on the carrier, and the spray or toxic soil should be even. (3) "San Zhun": the time of application, the amount of application, and the area of ​​the applied plot. For example: use 33% of weeding emulsifiable concentrate 150-180 ml per acre, add 60 liters of water, spray before the seedlings of ginger. 5. Remediation measures for herbicide phytotoxicity strengthen field management. For the phytotoxicity of the field should be strengthened management, combined with watering, increased application of quick-acting fertilizer such as urea; strengthen cultivating loose soil, break soil compaction, enhance soil permeability, increase ground temperature, promote beneficial microbial activities, and accelerate the decomposition of soil nutrients To enhance the absorption of nutrients and water by the root system, so that the plants can resume growth and development as soon as possible, and reduce the damage caused by the phytotoxicity; at the same time, the surface should be sprayed with 1%~2% urea or 0.3% potassium dihydrogen phosphate solution 30~50kg. /mu, China Pesticide Network recommends that Yingtian No. 2 multi-functional biological preparation 600 times liquid, promote crop growth and development, and resume growth as soon as possible.
