Studies were carried out in the laboratory to determine the toxicity of three commonly used fungicides (carbendazim, captafol and captan) against apple scab in Himachal Pradesh to the adults of two important Hymenopterous parasitoids of San Jose scale, viz., Encarsia perniciosi and Aphytis sp. proclia group. Results revealed that carbendazim 0.025%, captafol 0.16% and captan 0.15% were not toxic to the adults of either E. perniciosi or Aphytis sp. proclia group. There were no significant differences in the mortality and longevity of adult parasitoids or both the species in treated and control batches.

Abstract


Studies were carried out in the laboratory to determine the toxicity of three commonly used fungicides (carbendazim, captafol and captan) against apple scab in Himachal Pradesh to the adults of two important Hymenopterous parasitoids of San Jose scale, viz., Encarsia perniciosi and Aphytis sp. proclia group. Results revealed that carbendazim 0.025%, captafol 0.16% and captan 0.15% were not toxic to the adults of either E. perniciosi or Aphytis sp. proclia group. There were no significant differences in the mortality and longevity of adult parasitoids or both the species in treated and control batches.
