Product Overview

Rycar Insecticide brings a unique chemistry to a grower’s toolbox. Rycar provides excellent control of whiteflies (all biotypes), aphids, mealybugs, chilli thrips and leafhoppers. Rycar acts via contact or ingestion to stop insects from feeding within 2 hours after application before starvation sets in during the next 48 hours.

As versatile as Rycar is, it is also very gentle to both beneficial insects and pollinators. Rycar is the perfect alternative to neonicotinoid chemistries and is a great component of a comprehensive, economical IPM program.

How Rycar Works

Target pests exposed to Rycar via contact or ingestion, stop feeding within 2 hours. Rycar’s behavior modifying effect immediately sends the insects into a disoriented state (ataxia) where they are unable to eat and struggle to fly and crawl normally. Mortality of the target insect follows within 48 hours. Bottom line, Rycar works quickly to stop pests from eating your profits!

Rycar’s fast acting behavior modification not only prevents further crop damage due to the rapid stop-feed, but the immediate impact also stops the pests from traveling from plant to plant. Reducing insect movement significantly reduces vector-virus transmission. As vector-virus transmission continues to trouble more and more growers, Rycar becomes an irreplaceable tool.

Rycar in the Plant

Rycar's Translaminar Activity allows penetration of the waxy leaf cuticle and movement inside the plant leaf. When piercing-sucking pests feed on treated leaves, the target pests ingest Rycar and are subject to its affects. This provides an enormous benefit when controlling those hard-to-reach pests that feed from the lower leaf surface (abaxial). After application, Rycar can provide 21 days or more of control. To sum it all up, Rycar provides complete leaf protection.

Beneficial Safety

As aggressive as Rycar is against insect pests, it is just as gentle on beneficial mites and insects. Beneficial insects play an important and growing role in a complete IPM program. University and IR-4 research has shown Rycar to have no effect on Hypoasis miles, Amblyseius species, Orius species and pollinators among others.
