Third, the growth agent Seed dressing with 0.5% or 0.2%-0.3% potassium dihydrogen phosphate for dryland dragons can be used to provide seedling rate, promote wheat seedlings to accelerate excavation, and also enhance wheat's own disease resistance and reduce the chance of pathogen invasion. Fourth, the pesticide seed dressing matters 1. The dosage of seed dressing must be strictly in accordance with the requirements. Generally, the pesticide should be diluted with water to the required solution, then spray the liquid evenly on the seed with a sprayer, and spread it out for 4-6 hours.

If it is to prevent diseases such as mites, underground pests and rust, you can use 60% imidacloprid suspending agent seed coating agent (high-tech) 30 ml + 6% tebuconazole suspending agent seed coating agent (Like Xiu) 10 ml, add water 0.3- 0.4 kg, coated 15-20 kg prevention. 10mm Monopolar Laparoscopy Forceps 10mm Laparoscopy Forceps plastic and steel Tonglu WANHE Medical Instrument Co., Ltd , https://www.tlvanhurhealth.com
