Zero spraying for early season crop
Monitoring of psyllid populations demonstrated that numbers only begin to increase from early summer, because of cold weather and natural predator activity. From early January, numbers dramatically increase.
In the Pukekohe region, potatoes that are harvested in the pre-Christmas period, mostly early season fresh potatoes, do not need spraying to control the tomato-potato psyllid. Eliminating chemical control application for early season potato crops is estimated to have saved growers more than $300 per hectare.
