Key pests to watch out for

SEE ALL PESTS

Ryegrass - Annual

Annual ryegrass (Lolium multiflorum) is an important cultivated grass species which becomes a very competitive weed when growing in cultivated crops. Generally germinating at the same time as the crop it grows quickly and competes aggressively for space, light, nutrients and water.

Vulpia Hair Grass

In New Zealand three species of Vulpia (Vulpia spp) are found and being very difficult to identify they are collectively known as vulpia hair grass (VHG) or silver grass, rat-tail or squirrel-tailed fescue. Left uncontrolled VHG is a very aggressive weed leading to very serious yield losses and reduced seed quality through contamination.

Annual Poa

Annual poa (Poa annua), also known as annual meadow grass, is a fast growing annual grass found throughout New Zealand in a wide range of crops. While individual plants tend to be small, populations of this grass weed tend to be large and they then compete for light, nutrients and water.
