Abstract

Snails are important pest for a wide range of fruit orchards, ornamental plants, vegetables and field crops in India. They tend to feed on the softer parts of plants causing feeding damage to plant seedlings, with irregular holes in leaves, roots, tubers and fruits, decrease yield or cause loss of quality. Hence under such circumstances, a field experiment was conducted to evaluate the bio-efficacy and phytotoxicity of metaldehyde 2.5% dry pellet against snails in cabbage during Rabi, 2020, and Kharif, 2021. The treatments were: T1- Metaldehyde 2.5% dry pellet @ 12.5g a.i./ha; T2- Metaldehyde 2.5% dry pellet @ 37.5g a.i./ha; T3- Metaldehyde 2.5% dry pellet @ 62.5g a.i./ha; T4- Metaldehyde 2.5% dry pellet @ 87.5g a.i./ha; T5- Carbofuran 3% GR @ 30g a.i./ha; T6- Thiodicarb 75% WP @ 1-1.3g a.i./ha; T7- Untreated control. Results revealed that among the different treatments Metaldehyde 2.5% dry pellet @ 87.5 g a.i./ha recorded significantly zero snails as compared to 6.00 in untreated chec

Conclusion

Based on the evaluations it can be concluded that the insecticide Metaldehyde 2.5% dry pellet @ 87.5 g a.i./ha was found effective in reducing the snail populations and obtaining a higher head yield. Further, it had less impact on natural enemies and did not cause phytotoxicity to the cabbage crop. So Metaldehyde 2.5% dry pellet @ 87.5 g a.i./ha can be used for the effective management of snail pests in the field.
