The symbiotic period of the elongation of garlic and garlic and the expansion of garlic requires sufficient water and nutrients, as well as less high ground temperature. Therefore, according to different plots and different disease levels, fine management is required. For normal disease-free plots, water should be poured and poured, and the compound fertilizer or soluble alginic acid with good fertilization or solubility, such as humic acid and amino acid fertilizer, should be 10-15 kg. Unwatered fertilization plots are mostly heavy rickets, should be poured with small water, apply soluble alginic acid (humic acid, amino acid) fertilizer 5 to 10 kg per mu, and carry out foliar topdressing, spraying foliar fertilizer or 0.5 % urea + 0.3% potassium dihydrogen phosphate dilution, spray once every 5 to 7 days. As for the heavy rickets, that is, the yellow leaves are heavier, the water should be watered in a timely manner, first foliar topdressing, spraying foliar fertilizer or 0.5% urea + 0.3% potassium dihydrogen phosphate dilution, 5-7 Spray once a day, watering at the right time.
The integrated control of pests and diseases cannot be ignored. A fungicidal fungicide should be applied before and after watering. A bacterial fungicide such as iprodione or methyl thiophanate plus neomycin, combined with a foliar fertilizer to prevent the occurrence of garlic disease.
For the control of garlic heavy yellow (yellow leaf) disease, bacterial fungicides such as neutrophin and chlorhexidine can be used, and fungal fungicides such as Baitai and Duon are used alternately with foliar fertilizer, 5~ Spray once every 7 days.
In addition, 500 ml of phoxim emulsifiable concentrate per acre can be combined with 50 ml of avermectin emulsifiable concentrate or 500 ml of chlorpyrifos emulsifiable concentrate for controlling garlic root lice and root mash.
