| Abstract | Azolla is a bio-fertilizer which is used as a green manure. Azolla grows vigorously by means of asexual or vegetative reproduction. When azolla is in a proper environment, its production as green manure is approximately 3 ton/rai which contributes as 5-10 kg N/rai. However, using azolla as green manure is unlikely acceptable in Thailand because azolla is easily imfested by insects. Thus, this study was established to compare three kinds of biological control products which are environmental friendly. There were neem extracted substance (azadirachtin, Aza), Bacillus thuringiensis (Bt) and entomopathogenic nematode (Steinernema carpocapsae, Sc). It was found that among the biological products used in the experiment, Bt corporated with Steinemema carpocapsae (Bt+Sc) were the most effective product on Azolla?s insect caterpillars control. As a result, the highest azolla production was gained. For other products namely Bt, Bt+Sc+Aza and Bt+Aza were less effective on the caterpillars control, Respectively. |
