Target Crops » Should be used in combination with other Bioline products to help control a range of pests.

Key Features

  • Provides a cleaner crop because biocontrol products are not applied directly on the crop.
  • Reduces waste from product rolling off leaves.
  • Strong carboard box designed to withstand life in a commercial crop.
  • Robust hook to reliably hold box in place.
  • Wide opening for easy dosing of product.

How It Works

  • URBs hang directly on the crop and can be used to hold any biocontrol products which are available as dry-bulk-materials and which would otherwise be applied directly to the crop. By using URBs you can avoid applying products directly to the leaves and therefore prevent residues from the carrier materials. Additionally, URBs will reduce waste caused by product rolling off leaves and onto the floor of the crop.

Available Delivery Systems

  • URBs are sent fully assembled and ready to use. 50 URBs per unit.

Handling & Storage

  • Instructions for use: Remove outer packaging. Hang box directly on the plant using hook at top of box. Apply loose biocontrol products into the box Use at regular intervals adjusted to suit the release rate of the intended product(s). Avoid hanging boxes in direct sunlight.
  • Store & Transport: Store in a dry location until ready to use.
