Supply of Nematodes: Steinernema carpocapse infective juveniles

Descriptions

The pine weevil Hylobius abietis is a common cause of mortality in young conifers used to restock forest sites after clearfelling. Insecticides are usually needed to protect trees during the vulnerable establishment period and these are applied either before or after planting. However, there are concerns about the effects of insecticide use in forests on the wider environment. Recent changes in application technique as well as in the insecticide used, are a reflection of these concerns and of the need to reduce the use of chemicals in forests. Minimising the use of insecticides for the control of pine weevils requires the adoption of Integrated Pest Management (IPM). The IPM is a well-established approach to control that emphasises the value of releasing natural enemies such as nematodes for the biological control of weevil larvae.Therefore, the supply of these nematodes (Steinernema carpocapse infective juveniles) is required, packed in sealed units each containing no less than 3 billion live nematodes and around 1 litre in size. Higher numbers per pack will be accepted but will not contribute to the total contract supply.The product must be in a formulation that is non-hazardous to human health.The formulation product must be compatible with the wetting agent ‘AffinityTM.’The formulated product must have a shelf life of at least 3 months in refrigerated storage.THE FORMULATED PRODUCT MUST BE LICENCED TO USE IN FORESTRY IN ENGLAND AND WALES during 2016
