Treatment of Planthopper on Pandanus

Or browse by topic

Browse by date

Over 8–11 June, members of the Lower Mary River Land and Catchment Care Group, Don Bradley, Lesley Bradley and Janet Price, treated 160 Pandanus plants at Kingfisher Bay Resort and Beach Front against infestation by Jamella australiae (Pandanus Planthopper). An effort was made to locate all plants at the resort.

In addition to the 160 plants treated, 25 plants were found to be infected with Jamella, including three in very poor condition; a further three dead plants were found. Treatment was with 50% Confidor, and involved injecting trunks and low braches, or in the case of smaller plants, spraying leaves and squirting the crowns. Size of tree and type of branching determined the number of injections per tree: trees head high received one injection; taller, single trunk trees received two injections; trees branching up high received three injections; and large trees branching received two injections per branch where branches could be reached. Infected trees were marked with blue paint.

Funding for this project was supplied by a BMRG-Chemical grant, and thanks go to QPWS for supplying the Sidewinder tool and training for the injections, and to Kingfisher Bay Resort for providing barge passes and accommodation.
