SPLAT Verb is an environmentally friendly repellent that provides sustained and controlled release of the verbenone anti-aggregation pheromone. Verbenone is naturally produced by MPB and by several other species of bark beetle towards the end of a mass attack. The presence of verbenone signals new MPB approaching the infested tree that it is already too overcrowded to serve as a suitable host. By applying SPLAT Verb to a healthy and uninfested tree, host-seeking MPB will identify a tree as an undesirable host and leave it unharmed. Field studies have shown SPLAT Verb to be highly repellent of MPB on both single-tree and small stand levels. SPLAT Verb is an outstanding alternative to standard MPB treatments, due to its high-level of control, long field life, and simple application methods.
In a recent study on SPLAT Verb efficacy on individual lodgepole pines, there was a zero percent mortality rate on trees treated with SPLAT Verb, compared to a 93% mortality rate in untreated trees. In small stands, treatment with SPLAT Verb proved nearly twice as effective as an alternative verbenone product and reduced tree mortality compared to an uncreated control by a factor of 6.
