Actara gains extension of use for western flower thrips control

The HDC has published a new Extension of Authorisation for Minor Use (EAMU) 0186/2014.

The Chemicals Regulation Directorate has allowed the use of ‘Actara’ (M13728) as an insecticide for the control of western flower thrips (Frankliniella occidentalis) on protected ornamentals. The product contains 250g/kg thiamethoxam.
Neither the efficacy nor the phytotoxicity of the product for which this EAMU has been granted has been assessed and, as such, the user bears the risk in respect of failures concerning its efficacy or phytotoxicity.
The product is to be applied via horizontal boom sprayer or hand held sprayers in a volume of 500 to 2,000 litres per hectare, depending on the crop size and stage of growth. Applications should be made at 7 to 14 day intervals.

Growers are advised to test a small area of the crop prior to widescale commercial use.

It says growers should not clean application equipment near surface water and to avoid contamination via drains from glasshouses, farmyards and roads.

Use no more than two applications of any neonicotinoid insecticide (e.g. clothianidin, thiamethoxam, imidacloprid or thiacloprid) on any crop per year (and per structure in protected situations). Where a neonicotinoid insecticide has previously been used as a soil treatment, use no more than a single foliar application of any neonicotinoid.

This includes consideration of sequences involving soil treatments followed by foliar sprays. Where a neonicotinoid soil treatment has been used, the first subsequent foliar spray should be a non-neonicotinoid containing product.

Treated plants may not be put outside until after they have finished flowering.

When applying this product under the terms of this Extension of Authorisation, comply with any resistance guidance or restrictions stated on the product label.

I will not be importing oaks this season. Will you?

I find myself in a difficult situation. A few weeks ago I was fortunate to be present to hear details of imminent changes to regulations concerning Oak Processionary Moth (OPM) and oak trees. I heard details, asked questions and probed the implications of these changes. That may not sound like a difficult position to be in, yet I am uneasy.

Lobby groups jumping onto fashionable campaigns, often to promote their own interests, can do much more harm than good. Take, for example, the move against black polythene plant pots and containers.
