Canker forecasting launched at show

Agronomy services provider Agrovista launched a new apple tree canker forecasting service for growers at the National Fruit Show.

"Our growers are already using Growers Choice Interactive to forecast scab and codling moth and this year we are introducing a new model for Nectria, based on rainfall and humidity," said Agrovista horticultural consultant Alex Radu.

"It should be used in combination with the number of wounds on the tree from pruning, thinning or hail. Spores are released throughout the season and there is potential for infection so long as there are wounds on the tree, though that potential is greater later in the season when it's more humid."

The package takes in rain data from Agrovista's network of weather stations. "The grower can then decide whether action is required," said Radu. "There are many fungicides that will give you some protection."
