Even with crop protection, 20 percent to 40 percent of the world’s food is lost every year to pests. In rice, which is grown both for subsistence and export, these kinds of losses can be economically devastating and can jeopardize food security. By enabling early control of planthoppers, Pyraxalt™ active helps farmers protect vital rice crops in a way that is both sustainable and highly effective. Pyraxalt works at very low use rates compared to other commonly used planthopper insecticides, and it has minimal impact on beneficial insects. With innovative active ingredients like this, farmers can reduce their environmental footprint and grow bigger, better harvests to feed their families, communities and the world.

Harvesting confidence
A grain of rice tips the scales at a mere 20 milligrams. Yet each tiny grain carries a tremendous weight, upholding time-honored traditions, proud family legacies and dreams for the future.
In rice farming, there is no such thing as a simple season. Cultivation is labor intensive, and plants are especially vulnerable to insect damage. Planthoppers are one of the biggest threats to rice, with their ability to quickly destroy whole harvests. Controlling planthoppers can be the deciding factor in a season’s success, and a farmer’s long-term economic viability.
Pyraxalt™ active is a highly selective and effective option for planthopper control in rice. When used early in the season and once economic threshold has been reached, Pyraxalt protects rice against planthopper infestation for up to 21 days, helping farmers improve yield. This long-lasting, reliable control means farmers can spend less time in the field, while remaining confident their crop is protected from these damaging pests and growing to its full potential.
Transforming planthopper control
Planthoppers are extremely efficient in their ability to destroy a rice crop. Multiplying rapidly, they devour the nutrients in green rice, and their feeding can also transmit plant diseases. By the time farmers see yellowing patches in the field or observe even moderate numbers of the tiny insects, yield is already affected. Left unchecked, planthoppers leave behind “hopper burn”—swaths of brown, dry, wilted plants that are potentially unharvestable. Pyraxalt™ active gives farmers a new option to prevent this kind of potentially catastrophic damage.
Pyraxalt is used early in the season to gain immediate control over planthoppers. When applied at the very earliest stages of infestation*, it provides fast-acting control that lasts up to three times longer than other commonly used pesticides. Insects stop feeding quickly, preventing crop damage and reducing possibilities for disease transmission. The long-lasting efficacy of Pyraxalt also protects against the severity of the next generation of planthoppers, for better control throughout the season.

Fewer applications, more confidence
Pyraxalt™ active improves confidence in the season while reducing some of the labor around planthopper control. Products containing Pyraxalt are used when rice is young, making scouting and application easier. With up to 21 days of planthopper control, products containing Pyraxalt only need to be applied once per season, followed by a product with a different mode of action. By using Pyraxalt first, farmers protect rice during its most productive stages and when planthoppers can be the most destructive. Pyraxalt specifically targets planthopper species, so it has minimal impact on beneficial organisms. Natural enemies of planthoppers continue to thrive in treated fields, which helps provide an additional, valuable layer of biological suppression.

Early and long-lasting protection
Early application is critical to controlling planthoppers. During early stages of infestation, planthoppers are barely visible, even though they are already feeding and causing damage. As the canopy closes, they become harder to see and treat. Pyraxalt enables farmers to manage planthoppers earlier than other commonly used insecticides, for fast-acting planthopper control that also reduces the severity of next-generation infestation. With less insect pressure, rice plants have access to more nutrients to reach their genetic yield potential, bringing in more bushels and heavier grains at harvest.
Highly selective
Pyraxalt works to control all major species of planthoppers in rice. Its selective activity means Pyraxalt has minimal impact on non-target organisms that are important to rice cultivation, including pollinators, earthworms, fish and beneficial insects and spiders that feed on planthoppers.
New mode of action
Pyraxalt effectively controls species of planthopper, including those with demonstrated resistance to other commonly used insecticides. Pyraxalt works differently on a key binding site in target pests, triggering a distinct physiological response that makes it effective against all major planthopper species and across the pests’ damaging life stages. Having an active ingredient that works differently also helps protect the efficacy of other insecticides, so farmers can continue to have the options they need to control planthoppers.
A new approach for new possibilities
When farmers choose to use PyraxaltTM active first and early in the season, the results can be transformative. With Pyraxalt, farmers can forego regular scouting for up to 21 days and they don’t need to anxiously watch their fields for damage after application. As grains fill, they can feel confident planthoppers are under control, enabling a great harvest. With this peace of mind, rice farmers can put their focus where it matters most for themselves and their families.
