MULTAN: Agriculture experts have advised farmers to adopt proper safety measures to keep guava fruit protected against fruit fly attack, according to a press release issued by the media liaison unit of the Punjab Agriculture Department here on Tuesday.
The statement said that the summer guava crop was more vulnerable to fruit fly attack. The fly penetrates its Ovipositor into the fruit and lay eggs. The eggs get hatched inside and the new born flies start feeding on the pulp. Experts said that farmers should collect the damaged fruit and bury it.
Methyl Eugenol and Protein Hydrolysate pheromone traps should be applied to control fruit fly. Another disease causes dryness of branches and trunk skin near the ground while leaves attain brown or yellow colour.
It also causes roots to rot and plant dies within few months. This disease is caused by fungus in roots. Farmers should avoid excess water application in such orchards.
Experts said, anti-fungus medicine be applied to the roots of the affected plants and all the affected fruit be collected from the ground and buried. Guava plants be irrigated in accordance with weather conditions and soil specifics.
According to an assessment, guava orchards need 12-15 times water applications in a year. Smaller plants should get water after short intervals while the grown up plants need more water. However, when fruit starts appearing, farmers should stop water application till the completion of fruit setting stage.
Summer guava crop is harvested from June end to August. Ripe fruit should be plucked twice or thrice a week. Since guava is a perishable fruit, it should be dispatched to markets soon after the harvest, experts said.
