Afterwards, as the seedlings grow, they gradually relax Zhasi.
Management Technology Anti-mise Maturation Abandoned Membrane After Covering Membrane, 40% Amethyst Formamide Wettable Powder 40 to 60 grams per Point, Water 4 to 5 Kilograms Manual Spray or Add 2.5 to 3 Kilograms of Motorized Mist, Control Blue Blight and blight. When seedlings and leafhoppers occur, spray 25% to 3g of 75% tricyclazole wettable powder with water every minute.
