At present, farmers' friends only use bicarbonate as a common fertilizer for crops, but they do not use it as pesticides to control crop diseases and pests. The method for using iron bicarbonate as a pesticide is described as follows: Use ammonium bicarbonate and copper sulfate as raw materials to make pesticides. Use hydrogen carbonate as 3.8 kg, and research into a powder of 0.5 kg of copper sulfate. Immediately after mixing, add 1 kg of lime and mix well. Put it into a container or an airtight nylon bag and seal it for 24 hours to make “copper iron powderâ€. When used, copper ammonium powder is diluted with water to 1200-1500 times the copper content to the "copper ammonium complex agent". To vegetables, cotton spray, not only can prevent fungal and bacterial diseases, but also play the effect of dressing fertilizer. Mix ammonium bicarbonate with farmyard fertilizers. When potatoes and sweet potatoes are planted, 20-25 kg of ammonium bicarbonate per acre is blended with the farmyard fertilizer and applied to the cultivation ridges to disperse and kill the seedlings that damage the seedlings. Before planting vegetable seeds and seedlings such as leeks, garlic, kidney beans, cucumbers, etc., use 25 to 30 kilograms of “gas fertilizer†and farmyard fertilizer to mix and deepen each acre. This can kill root larvae and ground tigers and reduce the damage caused by these underground pests. . Ammonium bicarbonate is diluted to spray the crop leaves. When fruits, vegetables and locusts occur, the "gas fertilizer" is diluted 80-100 times and evenly sprayed on the stems and leaves of these crops with a sprayer to kill the worms and reduce the diseases such as blight, verticillium wilt and other fungi, bacteria and viruses. Sexual diseases.
