Herbicides

Effective control of weeds

Weeds can deprive crops of nutrition, water or sunlight and inhibit their growth. They can also harbour damaging diseases and pests and contaminate the harvested crop.

The herbicides used to control weeds make up approximately half the world market for plant protection. They usually fall into two categories – selective and non-selective.

Selective herbicides

There are more than 15 different groups of chemical substances, each with varying modes of action. They can help produce significant yield improvements in major crops such as wheat, cotton and sugarcane. Ospray, through its relationship with Cheminova, has access to a product pipeline delivering advanced new herbicides ideally suited to Australian conditions.

Non-selective herbicides

These herbicides are used primarily in broadacre fallows and horticulture crops such as citrus and vines. They’re applied to weeds to conserve moisture, nutrients and reduce disease carry over.
