Fosthiazate10%GR nematode control,control of root-knot /insecticide/

Much of the research for nematode control with fosthiazate has been conducted on cotton, tomato, potato, and tobacco. Fosthiazate does not appear to have any systemic activity. Fosthiazate does control M. javanica but not as effectively as 1,3-D or fenamiphos. Integrated approaches of fosthiazate and1,3-D, or metam sodium provided control of root-knot and cyst nematodes similar to methyl bromide on some crops. Fosthiazate increased ratoon yields in pineapple following fumigation with Telone but was not effective itself as a preplant soil treatment. Yield increases have been reported in tobacco, banana, pineapple, tomato, and peanut following application of fosthiazate but were not always linked with nematode control. Yield increases were higher when banded applications were used rather than broadcast applications. Control of Meloidogyne incognita on sweet potatoes was not accompanied by an increase in yield due to phytotoxicity. The level of nematode pressure also determines the amount of control achieved with this compound. While fosthiazate effectively 110-1 controlled root-knot nematodes on spring tomatoes in Florida, it failed to provide similar control in the fall under higher nematode pressure.
