| Abstract | ||||
| This study was conducted at El-Mansoura district, Dakahlia Governorate during September – October 2011 on pea plantation to evaluate the efficiency of certain biocides compared with some Molluscicides against Monachasp.Land snails on laboratory and field. Results can be concluded that Biogard, Cranch, Protecto and Vertimec were used with 1, 2 and 3 % concentrations as leaf dipping technique. LC50 and LC90 values were (2.84 and 18.75 %), (1.97 and 4.57 %), (4.99 and 25.29 %) and (0.63 and 2.56 %), respectively. While LC50 and LC90 as poison bait fore mention before biocides were (2.04 and 37.3%), (2.08 and 5.97 %), (3.45 and 19.50 %) and (0.51 and 2.13 %), respectively in laboratory. Results of the field experiments showed that the tested biocides reduced Monacha sp. Population density on pea plantation with low values, except, Vertimec (83.32%) after 21 days residue effect. While Molluscicides were the most effective (up to 90 % ) to population density reduction of land snails infesting pea plantation compared with tested biocides compound. | ||||
