Application of Growth Regulators

 

Fruit drop During the developmental stage of berry, 10 to 50 per cent premature fruit drop occurs due to insufficient carbohydrate, auxin-carbohydrate imbalance, nutritional disorders and waterlogging. Many growth regulators have been tried to increase the fruit set and for controlling the pre-mature fruit drop. Following growth regulators could increase the yield when they are given as foliar application 10-15 days after blossom (first spray) and during last week of May before the onset of southwest monsoon (second spray).
