It is now approved for use on outdoor and protected grapes, apricot, plum, kiwi fruit, olive, chestnut, walnut, hazelnut (including cob nut and filbert), quince and protected blueberries.
The product contains insecticidal crystal proteins and spores from the naturally-occurring micro-organism Bacillus thuringiensis var kurstaki and helps growers control caterpillar pests. It is applied like a conventional insecticide - by mixing the recommended dose rate with water to give good coverage of the target crop.
For these new SOLAs, DiPel DF is applied with a conventional hydraulic sprayer, including air-assisted hydraulic and orchard sprayers, at a maximum individual dose of 0.75kg of product per hectare, in a minimum of 1,000 litres of water per hectare. The shortest interval between applications is seven days.
DiPel DF acts as a stomach poison on target Lepidoptera pests. The larvae or caterpillars feed on the treated foliage and stop feeding rapidly, dying within one to three days of ingesting the product, as with other insecticides. It has no resistance problems and is biodegradable, leaving no residues on the crop.
Growers need to obtain a copy of the notice of approval to use DiPel DF via the Chemicals Regulation Directorate website, ADAS offices or NFU. The SOLA reference number for DiPel DF is 2882 of 2010.
