BIOPEST® is a high-grade, paraffinic oil specifically developed and formulated to be safely applied to leaf surfaces whilst still maintaining insecticidal & fungicidal properties.
BIOPEST® has been extensively field tested in fully replicated, independent and internal field trials in a range of Australian winter crops. BIOPEST® has proven to be extremely effective in canola and cereal production as:
Field trials of BIOPEST® show it can be used as an insecticide to suppress populations of:
On small populations, BIOPEST® works to suppress insects in several ways. First, BIOPEST® physically smothers and suffocates insects, such as aphids and other relatively immobile pests. Second, it negatively affects their nervous system. Third, BIOPEST® slows population growth by coating the leaf surface and detering insects from colonising and laying eggs. Because these are physical modes of action, there is little to no chance of resistance developing in insect populations.
Finally, BIOPEST® generally doesn’t affect beneficial, predatory insects, such as predatory wasps, lady birds and bees, because they are more mobile and are not contacted during application. This allows beneficial insects to continue providing pest control in their own right, while affected pests provide a food source. Not using broad spectrum insecticides and maintaining beneficial populations, is the basis of an IPM strategy when using BIOPEST®.

BIOPEST® has been extensively trialled for insect control in canola and cereals, with results indicating that it is as effective as traditional insecticides. At the same time, it avoids the downsides of traditional insecticides including resistance development, impacts on beneficial populations and low user safety.

To simplify the use of BIOPEST®, SACOA have invested heavily in evaluating the incorporation of BIOPEST® into existing agronomic practices, as an adjuvant replacement with a range of herbicide actives and cropping systems.
Incorporating BIOPEST® into an early post-emergence herbicide application enables insect populations to be suppressed prior to numbers building. It also provides an anti-feed effect and some protection from low levels of early disease. BIOPEST® is no less effective than a standard adjuvant in controlling weeds, with a range of commonly used herbicides.
As a herbicide adjuvant alternative, BIOPEST®, being formulated from a paraffinic base oil, has a number of properties which make it effective at increasing herbicide performance including:

BIOPEST® is a high-grade, paraffinic oil specifi Blackleg and Sclerotinia in canola can be devastating for yield but can also result in the buildup of sclerotes in the soil affecting later crops. Given BIOPEST®’s proven fungicidal effects in a range of other crops, including bananas & pulses, BIOPEST® has been rigorously tested over the last four years as a carrier for common canola and cereal fungicides in a range of fully replicated, independent and internal trials.
The results show that BIOPEST® doubled the effectiveness of some fungicides giving yield increases of up to 350 kg/ha.
BIOPEST® improves the effectiveness of fungicides in three ways:

BIOPEST® manages insect populations by contact and smothering. It also deters feeding by reducing the attractiveness of leaves to pests. It is therefore important to apply early prior to insect populations developing and to ensure thorough coverage of both upper and lower leaf surfaces.
Always use BIOPEST® in relatively high water volumes (80-100 l/ha) with medium to coarse droplets to improve canopy penetration. BIOPEST® is an effective droplet modifier and will increase the average droplet size.
Ensure that the spray solution contacts the part of the plant with the heaviest disease and or insect pressure. This is particularly important for green peach aphids which tend to colonise the underside of leaf surfaces. Effective ways of getting coverage on the underside of leaves include setting up the boom to create turbulence or applying in a cross wind.
