| Abstract | ||||
| Insecticidal efficiency of some inorganic cupreous fungicides was tested against cotton leafworm larvae infested bean seedlings. The tested materials were Del cup (copper sulphate) 6% SL, copper oxychloride 50% WP and Champion (copper hydroxide) 77 % WP. The compounds were tested by 3 doses 0.5, 1.0 and 2.0 of their recommended rate as fungicides and sprayed using hand plastic sprayer 1 L capacity on bean seedling. Initial and latent toxicity against 2nd and 4th instar larvae also developmental effect against pupae and moth of cotton leafworm and antifeedent effect were studied. Results indicated that the tested fungicides showed slightly initial effect and high latent effect specially in case of copper sulphate and copper oxychloride against 2nd instar larvae enough to broke the life cycle of cotton leafworm, also the tested compounds showed antifeedent effects against larvae and the rate of their dose as fungicides is preferred for economic considerations. It could be said that besides using the tested compounds as fungicides, they could be considered as an element of IPM of controlling cotton leafworm. | ||||
