Siltac EC becomes very important in the woolly apple aphid control thanks to its two basic characteristics: excellent spreading on surfaces which are difficult to wet (e.g. a woolly apple aphid colony) and effective elimination of harmful insects by physical action.

According to scientific trials a single application of Siltac EC reduces the woolly apple aphid by ca. 65%. If the application is repeated after 2 weeks, the pests’ numbers fall by 90%.

Using Siltac EC mixed with traditional insecticides is very beneficial. As the research reveals, Siltac EC in half the recommended concentration (0.1%) mixed with an insecticide containing acetamiprid (full dosage) reduces the numbers of the pests by 90% after a single application. If re-applied, the efficacy was 100%.

Remember that Siltac EC enhances the performance of traditional insecticides in two ways.

Siltac EC is a very good tool in the woolly apple aphid control strategies. It may be applied on its own, but combined with traditional insecticides its effects are even better.
