Active Ingredients: 25g/l deltamethrin, 225g piperonyl butoxide.
K-Obiol is a liquid insecticide used in the agricultural industries to aid with controlling pests commonly found in grain stores. It is suitable for use on grains and pulses and the buildings they are stored in as well as the crop handling equipment used.
It is a non-foggable emulsion concentrate that requires dilution. The amount of dilution depends on the size of the affected area. For further instructions on how to dilute for the most effective result, view the label PDF in the Downloads tab.
The residual life of the treatment depends on the type of application and the surface.
Complete direct admixture with grain and pulses
For maximum efficacy follow ‘The grain storage guide’ published by the Home-Grown Cereals Authority (HGCA), the moisture content should be below 14.5% and the temperature below 12°C before admixture and during storage. Storage of grain with a higher moisture content will reduce the efficacy of the treatment. K-Obiol® EC25 is diluted with water and applied using low-pressure nozzles situated over the conveying machinery, as near to the final storage place as possible. The application rate should be adjusted to apply 1 litre of solution per tonne of grain/pulses. Dilute 1 part K-Obiol® EC25 with 99 parts water (1 litre of concentrate to 99 litres of water treats 100 tonnes of grain/pulses) to provide up to 12 months protection against listed crawling insects and up to 2 months against listed flying insects i.e. moths.
Treatment of storage buildings/equipment
There is no waiting period between treatment and use of buildings/equipment, however for maximum efficacy, treatments should be applied to a previously cleaned store, 3 to 4 weeks before filling. The performance maybe impaired on concrete surfaces. The store should be thoroughly swept or vacuumed to remove all loose fragments and previous stored crop waste that could shelter pests. This debris must be burned or disposed of well away from the building. Guidance on cleaning of grain stores can be obtained from the ‘The grain storage guide’ published by the Home-Grown Cereals Authority (HGCA). Use a knapsack sprayer equipped with a low pressure nozzle producing a medium to coarse spray. Absorbant surfaces (e.g.unsealed wood and concrete) - Add 20 to 30 ml of K-Obiol® EC25 to each 5 litres of water. Spray at a rate of 5 litres of solution per 50 sq metres. Non-porous surfaces (e.g. metal, sealed wood, sealed concrete) - Add 40 to 60 of K-Obiol® EC25 to each 5 litres of water. Spray at a rate of 5 litres of solution per 100 sq metres. The treatment provides 2 month protection.
Where strains resistant to deltamethrin occur or develop, effective control will not be achieved.
