Insect pests of cotton. 7. Effect of combined spray of pesticides, fertilizer and hormone on pest population, growth, yield and economic characters of cotton



Insect pests of cotton. 7. Effect of combined spray of pesticides, fertilizer and hormone on pest population, growth, yield and economic characters of cotton



Labdev J. Sci. Tech. (B) 6(3): 175-9. Bibl. 17



In trials with cotton, 2 sprays with urea (12 kg N/ha) + 5 ppm. naphthoxyacetic acid (NOA) + 0.02% phosphamidon and 2 further sprays with phosphamidon decreased jassid )infestation by 86.7% and increased seed-cotton yields to 1924 kg/ha, compared with 1658 kg/ha for untreated controls; other combinations of urea + NOA with 0.1% BHC + 0.1% DDT and/or 0.25% cuprous oxide were less effective.
