Inorganic insecticides are used commonly by farmers to control insect pests. Organic insecticides are the most healthy and environmental friendly and manufactured locally.
Right seeds
Find and select yellow neem tree seeds and dry them for 4 days to turn brown. Pound dried seeds to remove shells without breaking the seeds inside. Winnow to separate the shells from seeds. Classify and separated seeds basing on colour as good ones are dark. Pound seeds into powder and mix with water in container at a ratio 0f 350 grams to 10 litres. Settle the mixture for 24 hours and filter to remove particles that can affect the sprayer. Spray on crops at 50 cm above foliage.
