How do aquatic snails damage rice crops? Snails of the Isidorella newcombi and Glyptophysa sp. cause considerable damage to rice crops in Australia. They feed on the roots of the rice plants, causing substantial damage to the root system of the seedling.Snails damage plant growth and can cause a reduction in plant rice seed density. Snail infestation may cause slower maturity of the plant and variations in crop yield. When is snail infestation most likely to happen? Snail infestations often occur when a crop of rice is sown into a paddock used in a previous season to grow rice.Aerially sown crops are particularly susceptible to snail infestation as young plants have a shallow root system. Safety & Suitability Questions Is there a withholding period or restraints after Snailblitz application? Yes. Do not harvest for 80 days after final application.Also, do not release irrigation water from rice paddies for at least 28 days after application. Application Questions How can Snailblitz be applied? Snailblitz can be applied dry via aerial crop dusting. A recommended application rate is 6-12kg per hectare, though higher rates are suggested for deeper water or if high levels of organic matter are present.Alternatively, Snailblitz can be added directly to water in a spray mix. Where small areas of application are required (such as farm supply channels), it may be spread by hand. We want to do aerial application for snail pest control. Why should we use Snailblitz?
