Dont need much forecasting - small and backward crops of rape are rank with phoma or LLS.
Also smaller crops which had aramo on are now looking really poor. The leaves have thickened up and are like leather.
All are in line for a blast of Contrast and some foliar nutrients to try and keep them from giving up.
Only things still going are the slugs.
This is going to be a rotten rape year in the main.
