New insecticide to improve pest control in more stone fruit crops

MORE stone fruit growers now have a new insecticide in their “toolbox’’ following the extended registration of Cormoran for use in a wider range of crops.

30 June 2018

The unique insecticide, from Adama, incorporates a new mode of action using the active ingredients, novaluron and acetamiprid, making it a vital resistance management tool used in rotation with existing chemistry.

In addition to providing rapid, targeted control of codling moth and other key pests in apples and pears, it can now be used in a range of other stone fruit crops, including apricots, cherries, nectarines, peaches and plums.

It also provides control of apple dimpling bug, black peach aphid, green peach aphid, light brown apple moth, longtailed mealybug, oriental fruit moth, plague thrips, Sane Jose scale and tuber mealybug, and offers suppression of Mediterranean fruit fly, Queensland fruit fly and woolly apple aphid.

Late last year, Adama also combined Cormoran with the fully integrated and automated pest monitoring system, Trapview, in an innovative move to help growers further improve control of some of the major pests in pome fruit.  

Adama Head of Portfolio Dror Dagan said the unique package helped growers to better optimise the timing of Cormoran applications, resulting in superior efficacy, increased efficiency and cost-effectiveness, and potentially reduced insecticide applications.

The Trapview automated pheromone smart trap uses revolutionary technology to provide a simple solution for monitoring insect populations, as well as providing important temperature and humidity data, which can be modelled against set degree day parameters to predict pest cycles.


The system automatically photographs lured insects, processes the images and provides analysis of the situation on desktop computers and mobile devices, allowing advisers, agronomists and growers to be aware of pest pressures in near real time, without physically being in the field. Insecticide control options and specific application timings and rates can then be determined more strategically.

Insect population thresholds are determined using industry best practice and are based on target yield, quality and the market for the crop.

Meanwhile, fruit growers can also look forward to a new and innovative secondary fruit thinner from Adama expected to be registered soon.

Especially formulated for apples and with a unique mode of action, Brevis is tipped to revolutionise the way apples are thinned, giving growers the means to thin them more reliably and consistently, year-after-year.

“With much less temperature dependency and a wider window of application, Brevis solves the problems growers face with traditional chemical thinners,’’ said Adama Portfolio Manager Stuart Moncrieff, who is responsible for the company’s herbicide and plant growth regulator products.

Containing the active ingredient metamitron, together with calcium, Brevis disrupts the photosynthetic apparatus for seven to 10 days after application, reducing carbohydrates and leading to an earlier and increased natural fruit drop.

Cucurbit and fruiting vegetable growers will also be particularly happy to hear about a new solution for nematodes, which can severely impact crop development and yield and also expose crops to secondary pests such as soil-borne diseases.

Adama’s Nimitz nematicide, featuring another new mode of action, provides rapid activity on nematodes in capsicum, chilli, eggplant, tomato, cucumber, honeydew melon, pumpkin, rockmelon, squash, okra, watermelon, zucchini and sugarcane crops. A recent permit has also allowed its use in sweet potatoes and further registration for its use in other crops and areas across Australia is expected soon.

Dror said Nimitz contained the active ingredient, fluensulfone, making it a “true nematicide’’ compared with other standard nematode treatments.

Delivering irreversible activity immediately following application, it can be used to control root-knot nematode and/or root lesion nematode.

Dror said Nimitz had consistently demonstrated equivalent or better nematode control than standard treatments in trials and, in many cases, had resulted in a significant increase in marketable yield.

For further information on Cormoran, Trapview, Brevis or Nimitz, growers, advisers and agronomists can contact their local Adama representative.
