Pink worms have affected an area of 6 lakh hectares of Bt cotton in 11 districts of Saurashtra, where farmers irrigated and planted cotton before the monsoon rains. Severely pinkish larvae may be at greater risk if farmers plant early next year. So next year, farmers who grow cotton in 6-7 lakh hectares before the rain will face difficulties. In 2018, the Director of Agriculture claimed that in 2016, 2017 and 2018, M3 has brought pink worms under control. But it is attacked again after two years.
Currently pink worms have caused a lot of damage to cotton. The common belief is that no worm can live in BT cotton. Eating its leaves means fainting and dying. But it is not just green worm. But pink worms do a lot of damage. This time, due to widespread pink worms, cotton worth crores of rupees has gone bad.
The pink worm escapes from the egg and enters the developing gill. Therefore no insecticide works for him. This was because farmers could not go to the fields because it was raining, so they could not spray pesticides to kill pink worms.
Dr. of Agricultural Science Center of Junagadh Agricultural University. HS Godhani, KP Bairia cautioned farmers that pink worm infection is more prevalent in farmers who have already planted cotton. This is because fossils in the ground lay their eggs first in a favorable environment. Therefore, farmers should not pre-plant cotton next year.
Foreman trap measure
Pheromone trap should be applied before spraying. Spraying 80–100 g of Bavaria basia in a pump, trapping light. If 10 fungi are found, spray the insecticides Profenophos 40% EC and Cypermantrin 4% EC 15 to 20 ml in a pump. Fertilizer should be made by crushing cotton stalks. Do not keep it. Do not give last irrigation. To keep the goats in the field to graze.
Cotton in advance
In which 13 thousand hectares of cotton was planted in advance on 1 June 2020. In which Junagadh, Amreli, Somnath, Jamnagar and Surendranagar were ahead.
By June 15, 2020, 6 lakh hectares of cotton was planted before the onset of monsoon. 90 percent of which was planted in Saurashtra. Amreli had the highest planting in 2 lakh hectares of cotton. After that, cotton was planted in 82 thousand hectares in Bhavnagar, 82 thousand hectares in Rajkot, 43 thousand hectares in Botad. Cotton was cultivated in this way in all 11 districts of Saurashtra.
By 13 July 2020, cotton was planted in 20 lakh hectares. Which was 21 lakh hectares in 2019. The highest area of 3.3 lakh was planted in Amreli. Bhavnagar had 2.24 lakh hectares. 2 lakh hectares were planted in Radakuto. Thus, Saurashtra had 14.50 lakh hectares of cotton under cultivation, of which 12 lakh hectares are estimated to be Bt cotton.
Pink worms in ground oil
The oil is extracted from the hut in Gujarat. In which pink worms come in large numbers. Without removing it, some oil mills extract the oil and feed it. so be careful. Therefore ginning mills burn waste or make manure.
After entering the gindwa, the hole is filled. Jindwa, flower or wasp falls. Rupees. Quality deteriorates, oil percentage decreases. The vibrational power of the seed decreases. So the ginning decreases. Oils spoil. Cotton plants have more pink larvae in the late stage. The cotton plants left in the ginning factory are affected by pests. Translated from Gujarati
