New registrations for Trivor™

The APVMA has recently approved the use of Trivor insecticide for the control of a range of key pests in avocados, macadamias, mangos and grapes and included several additions to its registered uses in citrus.

Trivor can now be used for the control of Fruit/Banana spotting bug, mealybugs and scale in avocados, macadamias and mangoes and the suppression of fruit flies in avocados, citrus and mangoes.

In grapes, Trivor is now registered for the control of Light Brown Apple Moth, Long tailed Mealybug and Grapevine scale, providing growers with an excellent multi-pest rotation option.

Additional pests added to its use in citrus include the control of Kelly’s citrus thrips and Fruit/Banana spotting bug and suppression of Queensland fruit fly and Mediterranean fruit fly.

Adama Australia Portfolio Manager – Insecticides & Nematicides, Jonathan McDonald, says Trivor provides tree crop growers and their advisors with access to new modes of action and more flexible application timing for the robust control of key insect pests.

“Trivor delivers new modes of action that provide rapid knockdown and cessation of feeding on key stinging pests, such as Fruit/Banana spotting bug, as well as residual control on scale pests,” he says.

“Extensive trials have shown that Trivor sets new benchmarks in protecting marketable yield in avocado, macadamia and mango crops, as well as protecting bunches in both wine and table grapes.

“It will allow growers and advisors the opportunity to implement further resistance management strategies, both within the same crop season and from year to year.”

Jonathan says Trivor can be successfully incorporated into integrated pest management programs.

“Compared to common standard active ingredients, such as beta-cyfluthrin and trichlorfon, Trivor is less likely to flare secondary pests, such as mealybugs and scale, in avocado, macadamia and mango crops,” he says.

“Trivor should be targeted at early season populations and ideally, at the onset of crawler release in scale and mealybugs and used as part of a management program with rotation to other modes of action when required.

“When targeting Fruit/Banana spotting bugs, it should be applied when monitoring suggests activity in the crop or when indicator trap crops nearby suggest populations are present.

“It should be used as part of a management program for spotting bug control with rotation to other modes of action at a minimum 14-day spray interval when required.”

Trivor combines acetamiprid and pyriproxyfen, two highly effective and trusted active ingredients from the Group 4A and Group 7C insecticide groups, in a dispersible concentrate formulation.

It has excellent physical and biological compatibility with a range of other insecticides and fungicides for one-pass insect and disease control.

Trivor does not require the addition of an adjuvant to achieve maximum efficacy, providing excellent flexibility when implementing fungicide rotation programs.

“Biocompatibility and spray timing trial work is ongoing as new rotation option insecticides and fungicides become available, such as the recent registration of  Custodia® for husk spot in macadamias.

Trivor was initially developed by Adama to meet the needs of Australian citrus, grape, avocado, macadamia and mango growers.

“Almost 10 years ago, we identified an opportunity to replace products under regulatory pressure and improve rotational options available for growers and advisors in these key horticultural tree and vine crops,” Jonathan says.

“Trivor was developed from extensive screening in citrus and further identified as an excellent option in sub-tropical, tropical tree crops and grapes for controlling a raft of key pests.”

Adama is now pursuing commercial development throughout the world, including South America.
