Natria Lumachicida granular bait. Natria Lumachicida is a bait admitted in organic farming based on Ferric Phosphate, an active ingredient of natural origin commonly found in the environment. The granulated bait is particularly resistant to water. The snails and snails eat the bait and stop feeding and therefore damage the crops. Admitted in organic farming Natria Lumachicida applies to the first appearance of the snails by distributing the granules in a broadcast or on a perimetric band around the crops to be protected. It is preferable to distribute the granules in the evening when the snails are more active. Repeat the treatment when the bait begins to disappear. The dose varies depending on whether it is a broadcast treatment - use 2.5-5 g per square meter - or make a 1.5 m wide band along the perimeter of the crop - use 30g to protect 100 square meters.
