Diamond back moth is a major insect pest of cabbages and it is very difficult to control. The department of agriculture has identified a combination of insecticides that is presently effective to control the pest.
THE INSECTICIDES ARE:
- New Mectin
It is important that the insecticide is rotated to avoid the buildup of resistance. It is also very important that PH plus is always used with the insecticide. When PH plus is used there is no need to apply a sticker.
- It is important to count the number of active diamond back moth larvae (worms) per plant.
Samples of 20 consecutive plants should be counted.
2. When the average number of larvae (worms) per plant is one (1) or higher apply new mectin.
3. When the average number of larvae (worms) per plant is less than one (1) apply cascade or nbeem-x.
4. Remember to rotate cascade and neem-x.
5. All insecticide should be applied in the mornings or in the evenings.
6. Always apply PH plus to water before adding insecticide.
