Effect of different insecticides application on the lint quality of cotton
Bina Khanzada, Kamil Kabir Khanzada and Ahsan Hameed Khanzada
Laboratory studies were carried out on four insecticides Confidor, Polo, Proclaim and Deltaphose on lint quality characters of cotton. Cotton was harvested three times and lint of every picking was analyzed separately. Results showed that there was no significant effect of insecticides on lint quality characters such as micronair, fibre maturity, staple length fibre strength, seed index GOT and seed germination. First picking seeds had the overall germination percentage of 63.44 followed by second and third as 35.2 and 34.7%, respectively. There was no significant effect of the first two factors, whereas, the third factor, that is, picking time significantly (F=11.35; DF2, 78 P<0.0001) affected the cotton fibre strength. However, the time of harvesting significantly (P<0.001) affected almost all parameters of lint quality mentioned above. The highest values were recorded on first harvest of crops.
