Keep an eye out for mice

      Comments Off on Keep an eye out for mice

There have been reports of mice activity in some crops around the Central Highlands, including grain sorghum, mungbean and cotton.

Mouse populations have the potential to build rapidly and can do considerable damage in high numbers. Controlling plagues is both… Read more »

A new approach to silverleaf whitefly sampling

      Comments Off on A new approach to silverleaf whitefly sampling

The first major outbreak of silverleaf whitefly (SLW) in Australia occurred in 2001-02 in central Queensland. Although it hasn’t occurred again in such biblical proportions, SLW has spread across Australia and is still a pest to watch in many cotton crops, as the honeydew it secretes contaminates the lint. The original SLW threshold matrix developed in central Queensland recommended looking… Read more »

While ants are most often thought of as a nuisance in kitchens or at picnics, they can also be present in a wide range of crops and other farm areas.

Improved mirid spray thresholds for cotton

      Comments Off on Improved mirid spray thresholds for cotton

After the introduction of Bt cotton in the 1990s, the focus of cotton pest management has shifted to sucking pests. Green and brown mirid (Creontiades spp.) damage can occur at any stage, from seedling to boll filling, although crops are usually attacked before peak flowering. Feeding damage (including terminal death, abscission of young squares and bolls, and lint damage in… Read more »

Always read and follow the label when using agrochemicals

      Comments Off on Always read and follow the label when using agrochemicals

While agrochemicals are an important component of many pest management programs, care must be taken to ensure that any spray operations use registered products that are applied according to the product label. The manager of an Emerald farm has recently been fined $10,000, pleading guilty to a breach of the Chemical Usage (Agriculture &Veterinary) Control Act 1988 after significant levels… Read more »

Do I have a wireworm – true or false?

      Comments Off on Do I have a wireworm – true or false?

Wireworm adults and larvae are relatively common soil pests, attacking all field crops. Adults feed on germinating shoots, and larvae feed on germinating seed, seedling roots and shoots causing poor plant vigour or death. Wireworms are most common in zero till, areas with high stubble, or weedy fallows. These are habitats and food sources that sustain the beetles and enable… Read more »
