Pulwama, July 08: Horticulture experts have cautioned apple growers against undertaking deep pruning in their orchards during the ongoing heat wave, warning that such practices could leave fruits vulnerable to sunburn. Chief Horticulture Officer (CHO) Pulwama, Javid Ahmad Bhat highlighted the risks associated with heavy pruning in scorching weather.“Deep pruning exposes fruits to direct sunlight which may cause sunburn, ultimately affecting both yield and fruit quality,” he said. Bhat urged orchardists to exercise restraint and instead focus on maintaining adequate irrigation schedules to help trees cope with heat stress.“Irrigation in both high-density (HD) and traditional orchards during early morning or evening hours will be highly beneficial,” he advised.The official also touched upon the current status of fungal diseases in the region, noting that common issues like apple scab and Alternaria are largely under control at present. However, he cautioned that orchardists should not become complacent. Discussing pest dynamics, Bhat informed that field reports indicate populations of aphids, leaf miners, and mites remain below expected levels this season. “Infestation by these insects is significantly lower than what we anticipated given the weather conditions,” he said. Emphasizing judicious use of pesticides, Bhat appealed to growers to avoid unnecessary spraying.“Insecticides should only be applied when an actual infestation is noticed. Spraying without the presence of pests is both wasteful and environmentally harmful,” he stressed. He encouraged orchardists to regularly monitor their orchards to make informed decisions.Another concern raised was the potential for nutrient deficiencies, especially calcium, during prolonged heat spells.“Orchardists should watch for signs of calcium deficiency. If symptoms are observed, a calcium spray can be applied, preferably in the morning,” he suggested. Sprays during midday or evening should be avoided to minimize stress on the trees and maximize nutrient uptake.
