摘要

Background

Three nanoformulations were used against both the glassy clover snail, Monacha obstructa (Pfeiffer, 1842) and the white garden snail, Theba pisana (Müller, 1774) under laboratory conditions. These nanoformulations include chlorfenapyr, imidacloprid and silica. Silica was prepared from rice husk ash. According to zeta particle size, the sizes of nanoparticles were 99.9, 79.25 and 79.38 nm for chlorfenapyr, imidacloprid and silica, respectively. The zeta potential was 5.6, 11.1 and 30 mV, respectively. One-fifth of recommended field concentration was used for each nanoformulation.

Results

The obtained results showed that nanoimidacloprid was the most effective formulation against M. obstructa and T. pisana followed by chlorfenapyr and silica nanoparticles. The LC50, s were 10.3, 12.5 and 64.3 ppm, respectively, against M. obstructa; and 11.7, 14.1 and 79.2, respectively, against T. pisana. The efficacy of nanosilica wasn’t exceeded 40% with the highest concentration. These results found that chlorfenapyr and imidacloprid nanoformulations can be used against both M. obstructa and T. pisana. Silica nanoparticles can’t be used alone except combined with other nanocompounds.

Conclusion

Nanoformulations can play an important role in agricultural snails control and reduce the side effects of pesticides by reducing the concentrations used and thus reducing the harmful effects of pesticides on the environment.
