PROTECTION OF PLANTS SOWN AFTER CEREALS IN THE FERGANA VALLEY
Journal Title: International scientific journal Science and Innovation - Year 2023, Vol 2, Issue 11
Abstract
The following crops are mainly planted in the Fergana valley regions on vacant lands: corn (40.6%), white (black) sorghum and broom (13%), vegetable crops, potatoes, cabbage, root crops, legumes, etc. Among them, especially corn has a special place as a crop that will "collect" the cotton crop next year. In 2019, Ghoza tunnel gave 4 stages (generations) in its development, different from previous years. Since there were rainy days in spring and early summer (lower air temperature, higher humidity), the first generation, which usually hatches in early spring, was not observed. The butterfly flight begins in May and lays the first eggs on early cotton and other susceptible crops. When conducting biological control against bollworm in the corn field by determining effective control periods with the help of pheromone traps, by the 9th day: 35.8% from trichogram distributed twice, or 39.3% from trichogram distributed once, or bracon from trichogram (2 times) When used (1 time) - 50.0% biological effect was obtained. In order to achieve chemical protection of the maize crop from the cotton bollworm, a scheme of planting low-growing plants as an intercrop was tested (40 rows of maize + 8 rows of low-growing crops).
