N2  - A study on "Identification and management of pests and diseases of 
oyster mushroom" was conducted during 2002-2003 at the College of 
Agriculture, Vellayani. It was undertaken to investigate on the pests and 
diseases of oyster mushroom Pleurotus florida Eger as well as to evolve 
ways for tackling them. 
Springtail, flies and beetles were identified as pests infesting oyster 
mushroom. Springtail tSeira sp.) was the most dominant pest. Apart from 
this, mushroom flies, phorids (Megaselia sp.) and sciarids were found to 
cause severe damage. The beetle pest, Staphylinus sp. and an unidentified 
beetle belonging to family Staphylinidae and subfamily Scaphidiinae were 
also problematic. Pathogenic microorganisms were not observed but 
competitor moulds viz., Trichoderma spp., Aspergillus spp. and Coprinus 
spp. were present resulting in a reduction in the yield. 
In vitro studies revealed that dichlorvos 0.01 per cent and 0.02 per 
cent and malathion at 0.025, 0.05 and 0.1 per cent inhibited the growth of 
Pleurotus spp. 
The practices, which' prevented the entry of flies into the mushroom 
beds like covering the holes in mushroom beds with cotton and making 
pinpricks instead of holes on the cover, were effective in controlling the 
pest. Among the botanicals tested only garlic extract at two per cent 
proved effective. Chemicals such as dichlorvos @ 0.01 and 0.02 per cent, 
malathion @ 0.025, 0.05 and 0.1 per cent had inhibitory effect on 
Pleurotus if used in a spray schedule of three days interval in incubation 
room and 10 days interval in cropping room. Nimbecidine 2mlll though 
not very effective in controlling the pest could be recommended, as it 
proved not inhibitory to Pleurotus. A single spray of dichlorvos @ 0.01 
 
 
per cent three days after spawning can be recommended for controlling the 
pests affecting oyster mushroom. 
For managing Trichoderma spot application of carbendazim 50 ppm 
or lime were effective. Increasing pH of the soaking water from 6 to 8 
considerably increased the yield. This is an effective, cheap and 
ecofriendly recommendation, and can be practiced by the farmers.
