- grain weevils (Sitophilus granarius)
- flour beetles (Tribolium castaneum)
- grain borers (Rhyzopertha dominica)
- sawtoothed grain beetles (Oryzaephilus surinamensis)
- bean weevils (Acanthoscelides obtectus)
and flying insects such as:
- warehouse moths (Euphestia cautella),
- rice moths (Corcyra cephalonica),
- Indian meal moths (Plodia interpunctella)
- grain moths (Sitotroga cerealella)
IMPORTANT: This information is approved as part of the Product Label. All instructions within this section must be read carefully in order to obtain safe and successful use of this product.
APPLICATION: The residual life of the treatment depends on the type of application and the surface.
Complete direct admixture with grain and pulses
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 3 months against listed flying insects i.e. moths.
Treatment of grain 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 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). The performance may be impaired on concrete surfaces.
Use a knapsack sprayer equipped with a low pressure nozzle producing a medium to coarse spray.
Absorbent 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.
RESISTANCE Where strains resistant to deltamethrin occur or develop, effective control will not be achieved.
