[Narrator] When it comes to nematodes, the root knot nematode is the biggest problem in Arkansas soybeans. [Picture showing roots with nematode damage.]

[Picture showing a nematode magnified] University of Arkansas Division of Agriculture researchers Scott Monfort and Terry Kirkpatrick are focusing their research on two main areas: resistance and control.  [Picture of a soybean field] The researchers are studying 16 soybean varieties that have shown resistance to root knot nematodes in other states to see how they'll perform in Arkansas.

On the control side, Monfort and Kirkpatrick are looking at several nematicides including Temik and Vydate [picture showing Nematode Control - Temik and Vydate] that are widely used in cotton, and [picture showing Seed Treatments - Avicta (Syngenta) and VOTiVO (Bayer)] seed treatments such as Avicta and VOTiVO. Although these products are not currently labeled for use in soybeans in Arkansas, they may be options for some growers in the future.

Pre-planting fumigants, primarily Telone II, can be used two or three weeks before planting [picture showing equipment using pre-planting fumigants. Telone II, 2-3 weeks before planting; 8-12 inches; deep tillage; special equipment]. Fumigants must be injected eight to twelve inches into the soil, which requires deep tillage and special equipment. Because of both the need for specialized equipment, and the product cost, fumigants may not be cost effective for all growers.

[Picture of tillage equipment. Other Options - Crop rotation programs] Monfort and Kirkpatrick are also examining other options for producers including crop rotation programs that are both economically feasible and effective in lowering nematode populations.
