Benefits

Use Closer for quick and effective control of aphids, leafhoppers and scale insects in your vegetable, fruit and field crops.

Exceptional knockdown and residual control

Closer is effective in treating outbreaks and is valuable as part of an Integrated Pest Management program to minimize flare-ups. Isoclast™ active moves quickly through the plant and controls pests through both contact and digestion. Closer’s rapid results decrease the chance of virus transmission, which would otherwise damage both quality and yield.

Resistance management

Closer contains Isoclast active, the first active in a new class of insecticides, which is ideal for controlling insects resistant to other insecticide classes. The spectrum of activity and other properties of Closer insecticide makes it an excellent fit for Integrated Pest Management programs.

Control while maintaining beneficial populations

Isoclast is selective and has low impact on beneficial arthropods when used according to the product label.

Crops

Use Closer on a variety of horticulture crops for effective control of stubborn sap-feeding and scale insects.
