Welcome to the BioWorks Bulletin -- March 2014
This month we have information on how to protect your delicate plants from damaging root-feeding insects. Find out how beneficial nematodes safely protect your plants as well as your bottom line.
Controlling Root-feeding Insects
Root-feeding insect larvae can noticeably affect your bottom line. From creating root wounds susceptible to disease entry to reducing the water and nutrient uptake ability of the root system, these pests can set your crops back quickly. 

Fungus gnats are one of the most common culprits. Fungus gnat larvae can quickly build up damaging populations in the root systems of your plugs and other potted crops.

Outdoor nursery growers face losses in crops 
susceptible to attack from weevils (including black vine weevil, Otiorhynchus sulcatus) and other plant-boring larvae such as caterpillars.

Fear Not!
There is a proven effective, non-chemical response to these intrusions.
Beneficial nematodes Steinernema feltiae provide excellent control of fungus gnats when applied proactively, while the nematode
Heterorhabditis bacteriophora is effective in controlling losses due to plant-boring larvae.

How do they work?
These beneficial nematodes, once applied to the potting medium or soil, actively seek out insect larvae. They enter the insect through natural body openings or through the exoskeleton, then release a bacterium that kills the larvae within 24 to 48 hours. Eggs are laid, which hatch to produce a new generation of nematodes that search out the next insect victims. The life cycle is illustrated as follows:

Nematode Benefits
Pests don't develop resistance to nematodes. Repeated use of beneficial nematodes has not produced resistance among targeted insects. That makes them an enduring and truly integrated solution for pest control. Beneficial nematodes are versatile in that they are effective against many species of insects and can protect many varieties of commercial crops and plants.

These beneficial nematodes are also compatible with many pesticides, and can be applied with a sprayer or through an injector. They are safe around plants and people. Because they are classified as macro-organisms, no EPA regulatory warnings or restrictions are imposed upon their use.
Product Solutions for Root-feeding Insects
Keep your propagation program free of fungus gnats and western flower thrips (WFT) with NemaShield® (Steinernema feltiae). When used properly, NemaShield prevents fungus gnat outbreaks by attacking and killing developing fungus gnats in the potting media. For WFT control, NemaShield kills the prepupae and pupae in the soil, which will decrease adult populations.

Apply NemaShield® HB (Heterorhabditis bacteriophora) to safely and effectively protect against weevils and plant-boring larvae (caterpillars).

One grower's comments: 

"I have to give credit to RootShield PLUS. My plant loss this year has been minimal. I used to use different soil types for planting different items. This year I went 100% with Faford 2B Mix with RootShield PLUS. It was a big gamble, and it paid off!"
