Generally, there is no need to irrigate bulb onions at drilling time, but there are conditions when some irrigation will help establish the crop and make pre-emergence herbicides more effective. Likewise, during early season growing, it pays to water sparingly and carefully at the correct times.

A new system has been developed where weeds within a crop are detected using image analysis and specialised nozzles are then used to apply herbicides directly to the detected weeds. This factsheet gives an overview of the technology and helps growers understand how to use it.

The caterpillar of the silver Y moth feeds on foliage and pods and can cause a degree of defoliation when infestation levels are high. However, the main problem occurs when the caterpillar becomes a contaminant in vined peas, or when feeding damage to pods of fresh market peas or beans makes them unmarketable.

An assessment has been undertaken to predict the likelihood of pea bruchid (Bruchus pisorum Linnaeus) becoming a pest in peas and the impact that this would have on the crop. Factors such as its biology, likelihood of establishment and spread and the risk of economic damage have been taken into account.
