Good IPM starts in winter

By admin | Published: July 22, 2010
Farm hygiene underpins the successful management of a number of major pests. The recent appearance of solonopsis mealybug has highlighted again the importance of farm hygiene.

By admin | Published: August 23, 2007
Aphid control decisions tend to be more problematic in moisture stressed winter cereal crops, since in a well supplied crop the level of moisture extracted from the crop by aphids is of little concern.
