Whether you’re new to biocontrols or have an established program, finding new tools is important. Check out the latest bicontrol products available for your crop.



Nemasys And Millenium Beneficial Nematodes from BASF

Nemasys and Millenium beneficial nematodes help provide biological control of fungus gnats, Western flower thrips and shore flies. Beneficial nematodes are microscopic worms that attack and kill targeted insects without affecting any other organisms. Used as a stand-alone program or in rotation with conventional insecticides, Nemasys and Millenium nematodes are are naturally occurring and safe to humans, animals, plants and the environment.

Aphi-Mix System from Biobest

Biobest recently introduced its Aphi-Mix system targeting four major greenhouse aphid species in its product line. Populations of aphids can establish very quickly as they give birth to live young. Parasitic wasps are excellent in searching out the aphids in the greenhouse, but are very specific which aphid species they parasitize and control. Aphi-Mix system has a mix of four different wasps to cover the four major aphid species that are often found in greenhouse crops. The wasps are Aphidius colemani, Aphidius matricariae, Aphidius ervi and Aphelinus abdominalis. Aphi-Mix is available in bottles of 750 or 1500 pupae.

Aphid Guard from IPM Labs

Aphid banker plants produce a constant supply of aphids, which in turn support continuous reproduction of aphid parasites and the aphid midge. Greenhouse growers benefit by having a reproducing natural enemy population in the greenhouse that can find and attack pest aphids on the crop as soon as they appear. It also reduces their costs for regular shipments of natural enemies via overnight freight. Aphid Guard consists of densely seeded young barley plants infested with the bird cherry-oat aphid, Rhopalosiphon padi. These aphids do not attack broad-leaved plants.

Limonica (Amblydromalus limonicus) from Koppert

This super-aggressive predatory mite has already had a significant impact on biocontrol. First released in 2012, it’s the only predatory mite capable of consuming all larval stages of Western flower thrips, as well as the eggs and all larval stages of whitefly. Its value for IPM is further increased by its ability to feed and reproduce in greenhouse temperatures as low as 55°F.

Bioline Biological Agents from Syngenta

Bioline biological control agents (BCAs) are ideal for controlling pests as part of an integrated crop management (ICM) strategy. With a broad portfolio of BCAs and chemical controls, innovative packaging and a team of certified agents across the country, Syngenta Bioline makes ICM achievable for growers.
Produced in California, Phytoline p contains the predatory mite Phytoseiulus persimilis, a well-known predator of the red or two-spotted spider mite. It is effective in a wide temperature range and performs well in humid conditions.

MGS Horticultural USA

MGS Horticultural USA and its trained staff offers technical support and pest control products to flower growers to plan integrated pest management programs that combine beneficial insects, biopesticides and traditional chemistries along with defined strategies for successful results. This approach not only controls pests but also attains the end goal of shipping high-quality plants to the consumer. MGS does its own in-house quality control and stores the beneficial insects in climate-controlled coolers prior to shipment. Every week, fresh product is received and shipped back out within 24 hours. MGS has been providing successful biocontrol programs to its customers for more than 20 years.

On December 1, Eric Wallien of Roberta’s Inc. in Waldron, IN, officially purchased C. Raker & Sons in Litchfield, MI. The new identity of the company is now Raker-Roberta’s Young Plants, according to a Dec. 1 letter to Raker’s customers, suppliers, and business partners from Vice President Susie Raker-Zimmerman. “There have been minimal changes in management and we will be providing the same products and services on which we have built our reputation in the industry,” Raker-Zimmerman said in the letter, which also announced the name change and new logo. The sale of C. Raker & Sons was announced in September . A series of events affecting Raker’s financial situation caused the need for the operation to find an alternate solution. Roberta’s had been a customer of Raker’s since 2011, and the fourth generation, family owned grower-retailer was a fan of Raker’s commitment to quality. The agreement to purchase C. […]
