Few Applications, Outstanding Planthoppers Control in Rice
Something went wrong. Please try again later...
From nurturing seedlings in a nursery, to transplanting, to harvest, cultivating rice is a hands-on, laborious process for farmers. Rice farmers are conditioned to worry over their crops at every stage, and with good reason. Rice fields are vulnerable all season long—to weeds, diseases, weather conditions and, perhaps most critically, insect pests. Planthoppers are a particularly insidious threat to rice farms. These insects multiply rapidly, and unless farmers are scouting diligently, they may not even realize they have a planthopper problem until yellowing patches begin to appear in their fields, indicating grain and yield potential have already been lost.
Historically, the need for effective planthopper control has led to multiple applications of the same product, or products with the same mode of action, in a single season. Typically, treatment would not be initiated until planthoppers appeared in substantial numbers. Farmers would then fight back against generation after generation of these insects, often treating their crops frequently just to try to stay a step ahead of growing populations. This led to development of resistance against the most commonly used insecticides.
Today, Pexalon™ insecticide with Pyraxalt™ active is a new tool farmers can use to control planthoppers differently. Pexalon is one of several insecticides now available that utilize the active ingredient Pyraxalt to provide a whole new way to control these pests.
New mode of action for early, long-lasting control
Recommended to be applied after the earliest stages of infestation*, Pexalon™ insecticide is effective on multiple life stages of the pest. Using this insecticide early and on the first generation of planthoppers protects rice during a crucial development stage. Protecting the panicles as they form and develop eventually gives the plant the greatest potential to produce abundant, well-filled grain. Treatment with Pexalon is then followed by a product with a different mode of action to reduce risk of planthoppers developing resistance.

One treatment, three weeks of control
Pexalon™ insecticide allows farmers to treat their fields for planthoppers just one time and enjoy control that lasts up to 21 days. Pexalon penetrates into leaves, which gives it excellent residual control. In a series of trials, in 86% of cases, Pexalon provided better hopper control and more protection from hopper burn compared with typical farmer practices.1
Pexalon protects against all major species of planthoppers including brown planthopper, small brown planthopper, white-backed planthopper and green leafhopper. It acts quickly, controlling planthoppers through contact and ingestion of treated-plant sap. In one study, researchers found Pexalon controlled brown planthopper up to 6.4 times faster than other commonly used pesticides.2 The rapid reduction in hopper feeding has also been shown to reduce the potential severity of plant viruses.
Transforming planthopper control
Farmers who have used Pexalon™ insecticide are finding it gives them greater confidence and more freedom in their season. With Pexalon, farmers gain outstanding planthopper control with just a third of the applications they’re used to. They can eliminate the stress of continually scouting for pests and watching for yellowing patches in the field. Instead, farmers can put their attention elsewhere—pursuing other work to supplement income, caring for family and enjoying life—secure in the feeling that their crops are yielding, beneficial insects are thriving and they are doing their part to preserve crop protection technologies that will help keep planthoppers under control for many years to come.
