Shimla: The rising temperature has been turning out to be harmful for apple farming. The number of thrips—small insects—are penetrating apple orchards due to excessive heat. Experts believe that thrips in flowers are likely to ruin the crop. Climate change has changed the scenario of the horticulture sector. Apple growers have no choice except to wait and watch. The ideal temperature for proper apple growth is normally 16 to 20 degrees Celsius.
The ongoing weather is an important time for the setting of apples and pears. At the moment, moisture in the orchards is essential. But there is a lack of moisture in the soil due to a shortage of rain during the just-ended winter season. The population of thrips rises speedily in warm conditions.
Dr. Narendra Kayath, a horticulture expert and former head of agricultural sciences, warns that higher temperatures increase the risk of thrips in apple flowers. He advises orchardists to monitor their orchards closely during the flowering stage.
Farmers need to be careful in the use of pesticides. First, they need to select 50 flowers randomly. If the number of thrips is above 15 per flower, then use the pesticides. Experts never recommend the spray of chlorpyrifos, as it may increase the population of mites later.
Thrips are tiny insects seen on flowers and leaves. They are capable of producing almost eight generations annually. When the buds start blooming, the mites take place at the flower and ruin the pollen before it becomes mature, affecting pollination.
It is difficult to see thrips in sunlight. Agricultural scientists advise that you gently shake the flowers in the evening over your palm to find out their presence. Besides chemical sprays, it is necessary to maintain cleanliness and natural control methods for curbing thrips problems. Regular inspection and on-time action help in protecting crops.
