Detail:

Flower drop is common problem at the time of flowering of the cotton plant, the flowers fall down, resulting in reduction of total number of cotton balls. To prevent the flower drop, 500 g of the seeds of "padavela” are boiled in 10 L of water. Filter the decoction and spray over an area of one acre. The flower drop is stopped to the extent of 40 percent.
