Safe control of terristrial snails in Sugar beet (Beta vulgaris ) El - Sheikh Governorate At Kafr
Nadia Mohamed Mostafa Idrees;
Abstract
Several experiments under laboratory and field conditions had been conducted to study safety methods for population management of common land snails in sugar beet plantations at El-Hamool, Quallein and Sakha districts, Kafr El-Sheikh Governorate. The obtained results could be summarized as follows:
1. Monacha cantiana and Cochlicella acuta were the dominant species on sugar beet plants at the three locations, while Succinea putris was found in few numbers and slight infestation in the same localities on sugar beet plants especially which was near vegetables fields.
2. Sugar beet leaves were the most preferable for M. cantiana snails followed by lettuce and cabbage leaves. On the other hand, onion and garlic leaves were the most repellent food for M . cantiana snails due to repellent effect of taste and odor. Bran as a dry bait was the most preferable to M. cantiana snails followed by crushed wheat, crushed bread, crushed maize and crushed rice. When we use attractive materials as black sugar-cane molasses and vanilla, M.cantiana snails preferred bran with molasses more than bran with vanilla, while bran with onion juice was the lowest preferable followed by garlic juice due to its repellent taste.
3. The highest damage of different levels of M.cantiana infestation was recorded. General means of reduction in shoot weight were 68, 75, 86, 120 and 135 gm and reduction of root weights were 80, 86, 90, 120 and 156 gm when plants were infested with 10, 20, 30, 40 and 50 snails, respectively and reductions was increased when numbers of snails were increased.
4. The agricultural practices included soil cultivation and ploughing the soil, treated the seeds by systemic insectcide (Gausho ) , uses onion and garlic intercropped with sugar beet greatly reduced the attack of the snails M.cantiana and C. acuta to more than 50%.
5. The microbial compounds as Protecto, Bioranza and Spinosad were used as dipping and baits, then were estimated against M.cantiana and C.acuta under laboratory conditions.
6. The results showed that spinosad was the most effective to C. acuta than M.cantiana , while Protecto was the most effective to M .cantiana followed by Bioranza than C. acuta as a dipping method. On the other hand, protecto was the most effective for C. acuta than M.cantiana and Bioranza was most effective for M.cantiana followed by Spinosad than C.acuta snails under field conditions, the obtained results revealed that Protecto was most effective at high concentration followed by Bioranza, while Spinosad was the least effective.
