SUTERRA EUROPE BIOCONTROL

Characteristics In contrast to conventional treatments, this system has been developed to be active in the field for long periods:

Patented powerful attractants (BioLure® Unipack).Absence of direct contact between the insecticide and the fruits, and the devices are easy to remove from the field.Easy to integrate within MedFly control strategies. Ready-to-use devices.Officially approved for organic fruit production (EU directive 2092/91 Annex II).

Application Apply at a rate of 50 (in citrus) to 75 (in stone fruits and grapes) devices per hectareEfficacy may improve in areas of high populations if a greater number of devices are used.

DeploymentThe device includes a hook at the top for easy placement in branches. Devices should be hung as high as practical on the sunny side. Choose a strong branch which is not likely to break or be pruned before the end of the season Ensure the device is securely hooked onto the branch.Avoid placing the device near or above developing fruit to avoid direct contact between fruit and device.

We protect crops while protecting the planet.

We offer a highly qualified Technical Service.

Suterra is the world-leading provider of bio-rational products for crop protection and commercial pest control.

The best result: your fields pest-free.

Innovative technology for finding the best solutions.

This allows early control of Medfly, decreasing the population before the fruit be-comes susceptible.This also allows which reduces overwintering populations and initial pest pressure the next year.

MagMED trial data - Perth Hills AreaIt is important to understand the pest pressure on individual blocks and varieties and the influence from neighbouring areas as this will determine the number of MagMED required per hectare.MagMED• Used to suppress medfly population• Normally used at 50-75 per ha; depending on crop• In apricots, use 1 MagMED every 3-5 trees, up to 200 per ha.• MagMED and bait sprays are better than MagMED alone• Performs better than enclosed dry traps – less stung fruit• Cover spray when economic threshold number are achieved (see above)

All cover sprays had some effect on bees/bumble bees and beneficial insects and should only be applied when the economic threshold is triggered. In particular, thiacloprid is highly toxic to ladybirds, P. persimilis and lacewings, whilst little is known of the effect of clothianidin on beneficials.

3.5 New Technologies

3.5.1 Commercially available attract-and-kill devices

MagMED®

2012 season

In orchard 1, significantly more medfly (F = 6.69, df = 1 & 66, P = 0.012) were captured in the MagMED® plus cover spray (0.17 ± 0.07 f/t/d), than cover spray only plots (0.06 ± 0.02 f/t/d). In orchard 2, 2.2-5.8 times fewer medfly were caught in MagMED® treated plots (F = 24.81, df = 1 & 66, P < 0.0001) than the untreated control plots.

At harvest, in orchard 1, a higher percentage of infested fruits was recorded from the cover spray plots compared to MagMED® plus cover spray plots and difference was significant (F = 14.62, df = 1 & 66, P < 0.0001; Fig. 3.20). Similarly, in orchard 2, three times more infested apples were recorded in the untreated compared to MagMED® treated plots (F = 14.62, df = 1 & 66, P = 0.0003; Fig. 3.20).

Figure 3.20. Percentage of apples infested (visual inspection in-situ).

2013 season

MagMED® vs. untreated control

MagMED® did not suppress the male medfly population in the untreated apple orchard (Orchard 1; F=1.62, df=1 & 85, P=0.21). In orchard 2, fewer males were caught on MagMED® treated plots (F=4.71, df=1 & 99, P=0.03). However, female trap captures did not differ with treatment on either orchard (Orchard 1: F = 1.62, df = 1 & 85, P = 0.49; Orchard 2: F = 0.46, df = 1 & 99, P = 0.50).
