BIOPEST® has been the product of choice for pest control in many orchards for over a decade, with many unique characteristics including;
Orchard practices continue to change significantly with updated application technologies, removal of broad spectrum insecticides, the increased use of foliar fertilisers and export markets requiring IPM production practices. SACOA continue to invest heavily in research to keep abreast of these changes and provide BIOPEST® users with the best advice around product usage. Over the last 18 months SACOA have conducted field work investigating the following;
When using BIOPEST® for pest control, the following guidelines should be followed to maximise pest control and minimise the risk of crop damage.

Table 1: Mixing compatibility – This table provides an indicative guide to popular chemicals used in citrus that can be mixed with BIOPEST® (and possibly other mineral oils). Those that should not be mixed are highlighted.
Table 2: This chart shows recommended timing of sprays. Note: This is a guide only. Status of each pest varies regionally and monitoring is critical to avoid unnecessary or poorly timed sprays.

Recent trials conducted by SACOA over the 2015/16 summer have shown the benefits of BIOPEST® in controlling gall wasp in citrus (see Chart 1 & Figure 6). In this work, 3 weekly applications of BIOPEST® at 0.6% in 10,000L/Ha of water applied in Spring proved more effective than Actara in reducing gall wasp damage.
