Acelepryn

Full approval for the Acelepryn now covers control of Chafer grubs and Leatherjackets in sports pitches, golf greens, tees and fairways, golf roughs, racecourses and gallops, bowling greens, airfields, and professional application to commercial and residential lawns, subject to specific restrictions on the percentage of the area being treated. Applications should be made prior to egg hatch to achieve optimum levels of control. This period can normally be anticipated by monitoring for adult (beetle or crane fly) flight activity. When beetle or cranefly adult numbers are at their peak this is when ACELEPRYN should be applied to achieve the best results.

EGG LAYING PERIODS:

Leatherjackets

Tipula paludosa: Egg laying is likely to start in August and continue through to the end of September.

For optimum control apply Acelepryn when peak crane fly activity is observed, normally from the middle of July to the end of August. Later applications may not be effective as egg hatch may have already begun.

For Tipula oleracea there are two generations per year with adults emerging in August and September and a second generation with adults emerging in May to June.

Chafer grubs

Egg laying can start in May and can continue right through July. This is dependent on the species present and adult flight periods should be monitored to determine the best period for application.

For optimum control apply when peak beetle flight is observed. Later applications may not be effective as egg hatch may have already begun.

NOTE: Some chafer species have 2 or 3 year life cycles with overlapping generations. This means there could be 1^st instar larvae and mature 3^rd instar larvae in the same location. Where this occurs the mature 3^rd instar larvae will not be controlled. In these situations, it will require 2-3 years of Acelepryn use to gain full control of the Chafer populations
