Pest Program
A weather station in every field and a computer in the office can help fruit farmers in their annual fight against
the codling moth and other pests
The latest information on rainfall and temperature can be fed into
a computer program designed to zap
millions of insects which can wreck crops.
The program combines historical information about the growth of pests and weather data to predict – almost to the hour –
when the creatures might do greatest harm
. More importantly, it can tell fruit growers precisely when to spray pesticides and
reduce indiscriminate spraying
,which can prove costly to both the grower and the environment.
In the case of the pear sucker, which has almost destroyed the pear industry in some countries, the program can indicate precisely when to spray a selective herbicide
which will kill the nymph before it develops into a sucker
- but not affect the arithocorid bug, its natural predator.
