1. Dilute ammonium bicarbonate and spray on the foliar surface:
When aphids are found in fruits and vegetables, ammonium bicarbonate is diluted 80-100 times and sprayed evenly on the stems and leaves of these crops to kill aphids and reduce diseases , bacteria and viral diseases.
2. Self-matching pesticides with ammonium bicarbonate and copper sulfate:
Take 3.8 kg of ammonium hydrogencarbonate and 0.5 kg of copper sulfate which was ground into a powder. Immediately after mixing, 1 kg of lime was added and mixed, and sealed in a container for 24 hours to prepare "copper ammonium powder". When used, the copper ammonium powder is diluted to a "copper ammonium mixture" by adding 1200 to 1500 times of copper content. Spraying vegetables and cotton not only can prevent fungal and bacterial diseases, but also has the effect of topdressing.
3. Deep mixing with ammonium bicarbonate and farmyard manure:
When planting potatoes and sweet potatoes, mix 20-25 kg of ammonium bicarbonate with farmyard manure per 667 square meters (one mu) and apply it to cultivated ridges to drive and kill the cockroaches that damage the seedlings. Before planting seed or seedlings of amaranth, garlic, cowpea, cucumber, etc., use 25-30 kg of ammonium bicarbonate per 667 square meters and mix with the farmyard manure to kill pests such as root lice and small tigers.
