Recently introduced LCMSMS1 compounds
As part of our continuous improvement goals, we have recently introduced 4 new additions to our LCMSMS1 test, which means we can now screen for 56 separate chemicals in one analysis.
Spirotetramat is the active ingredient in Movento, which was introduced by Bayer at the end of 2008. This insecticide has a systemic action and translocates within the entire plant, in particular in new shoots and leaves. It is primarily used to prevent scale in important horticultural crops such as kiwifruit, as well as biting and sucking insect pests, such as aphids and mealy bugs on a wide range of crop types. It is safe for beneficial insects such as ladybirds however and recommended as part of an integrated pest management programme.
Spiromesifen, otherwise known as Oberon, was registered in New Zealand in 2009 and is mainly used to control mites, whitefly and psyllids. It’s mode of action works by inhibiting lipid biosynthesis which affects growth of early stage larvae and eggs and it is also very effective against insects resistant to other groups of insecticides, eg. neonicotinoids. It is not registered on a wide range of crop types in New Zealand yet, at present only Solanaceae family crops such as capsicum and tomatoes.
Spinetoram is chemically similar to spinosad, which is well known for its low toxicity and rapid breakdown in the environment. Marketed with the trade name of Delegate, spinetoram has been approved for use overseas on a wide range of tree fruits, including pipfruit. This chemical works well controlling codling moths, leafworms, thrips and caterpillars and has shown effectiveness up to 2 to 3 weeks after application. It is toxic to bees but once the spray deposit has dried on the plants, it should no longer pose a threat.
Chlorantraniliprole is the active compound in several new insecticides released recently, including Coragen and Voliam Xpress. It is a new type of insecticide, belonging to the chemical class of anthranilic diamides. It is highly toxic to butterflies and moths and also prevents caterpillars from feeding. It is not dangerous to mammals, fish or birds, though care should be taken that bees are not directly exposed, especially if there is more than one active ingredient in the formulation being used.
Hills have been monitoring these compounds for quite some time but have only introduced them as part of the reported coverage for the LCMSMS1 screen in the last 6 months. We frequently develop and integrate methods for new chemicals but if there is no demand from the New Zealand market for screening, then we don’t routinely report them.
So if you are interested in a particular compound that is not listed on our Food & Biological Pesticide Residue form (compound lists are on page 2), then please contact one of our friendly F&B client services managers to discuss your requirements.
