It will be the first full year of commercial use of the product which uses LOK + FLOW technology.

Speaking for Syngenta in Moses Lake, Don Drader, said: "It is a product that has two different modes of action. It has a new chemistry, mandipropamid, which is a completely new chemistry to potatoes. And also a second of mode of action in it is called difenoconazole. Difenoconazole has been registered in other crops in different parts of the world but this is the first commercial registration to potatoes."

Late blight has been predicted to hit the Colombian Basin again this year. But Drader hopes Revus Top, which has a pre-harvest interval of 14 days, will combat the problem.

"(It) locks or adheres very tightly to the leaf to give us the protectant and the flow or movement into the leaf to actually give us some curative or reach back of the product," he added.
