Chitter Paenibacillus produces an enzyme that breaks down the chitin layer around insect and nematode eggs. Also makes a hole in the shell where the shell meets the snail to let oxygen in which then causes the snail to die. Chitter can be used at 500ml to 1.5lt per Ha with any of our insecticides or nemacides for maximum control. Can be used 14 - 21 days apart for when insects goes into stress they release eggs which will need to be treated again.
