At this time of the year, glasshouse tomato growers in Western Europe are preparing to protect their crops against tomato enemy number one: whitefly. A good biocontrol strategy is based on the release of the beneficial bug Macrolophus pygmaeus. Macrolophus needs a couple of months to establish in the crop, especially when there is little or no prey-‘meat’ available. Therefore it is strongly recommended to provide enough extra food during the installation phase of Macrolophus in the greenhouse.
“By using our broad range of feeding products and following our specialist advice, it is perfectly possible to build up a strong army of beneficials which will be ready when the first pest insects arrive,” says Pascal Briand, sustainable crop management specialist at Biobest. NutrimacTM and Nutrimac PlusTM are made of tiny moth eggs, rich in protein. ArtemacTM is made of cysts of the brine shrimp.
Pascal’s general advice is as follows: “Growers should start feeding with NutrimacTM or NutrimacTM Plus on Macrolophus release points, followed by NutrimacTM Plus or ArtemacTM during 6 to 7 weeks after release. Both food supplements are suitable for Macrolophus adults and nymphs, depending on specific circumstances this general advice can be fine-tuned”.
