A new army of Biological control is being un-leashed this spring from Dragonfli. The move away from insecticides for garden pest control can be even faster now with many new natural solutions available for 2021. The use of nematodes is already popular with gardeners for pests like Vine weevil and this year many other insect pests can be controlled with this form of natural pest control.
One of the new Dragonfli nematode products is Asparagus Beetle Killer. The first generation of Asparagus beetle larvae appear on Asparagus plants during May and June. This is the time to apply Asparagus Beetle Killer nematodes, unlike many other nematode applications, the nematodes are sprayed directly onto the Asparagus beetle larvae on the plants. The nematodes then enter the larvae and kill them. This provides a new, safe and natural way to protect Asparagus plants from this damaging pest.
Other new nematode treatments include products for Gooseberry Sawfly, Viburnum Beetle, Codling moth and Plum fruit moth larvae.
It is not only nematodes that are multiplying , we also have new predatory mites and new ways of using them. One of our predatory mites; Amblyseius andersoni, was seen as a useful early season control of spider mites but recent trials has shown its use as a whitefly egg predator. It is also active at quite low temperatures for a predatory mite. This enables it to be introduced to plants when temperatures are to low for our standard whitefly control; Encarsia formosa. Whitefly can build to quite high numbers in low temperatures before temperatures are high enough for Encarsia to be active, by introducing our new Whitefly Killer Amblyseius andersoni in the spring , Whitefly development can be slowed down ready for the calvary to arrive in the form of Encarsia formosa when warmer conditions arrive.
