Type: article
Abstract: Experiments were conducted during rainy (kharif) season of 2003-06 on validation of integrated pest management technology in cotton (Gossypium hirsutum L.) at village Badgaon and adjoining area, Banswara, Rajasthan. The results of IPM technology were compared with non- integrated pest management farmers' practices which included 9-10 spray of insecticides. The IPM module recorded the lower population of aphids (Aphis gossypii Glower), jassi (Amrasca biguttula biguttula Ishida), whitefly (Bemisia tobaci Genna), thrips (Thrips tabaci Lindeman) and bollworms, viz. Earias insulana Fab. Helicoverpa armigera Hubner compared to non-IPM practices. The mean per cent damage by H.armigera and E.insulana (4.20 and 7.18) to square, flower (4.67 and 4.98), green boll (3.80 and 5.62), open boll (19.21) and locule (21.64) was found less in IPM fields as compared with non IPM fields which exhibited 6.68 and 10.11, 7.86 and 9.18, 6.42 and 10.38. 26.94 and 28.13 % damage, respectively. The seed cotton yield of 1 918, 1 804 , 1 820 and 1 780 kg/ha was recorded during 4 years in IPM fields as against 1 488, 1 504, 1 453 and 1 392 kg/ha in non IPM fields during 2003, 2004, 2005 and 2006, respectively. The IPM module also encouraged the population of natural enemies, viz Coccinellids and Chrysoperal carnea and spiders in cotton fields. The mean cost: benefit ratio in an integrated pest management field was 1:2.76 as against cost benefit: ratio of only 1:1.47 in non-IPM fields.
