Effect of spirotetramat and fluensulfone on population densities of and on peach.

Management of plant-parasitic nematodes (PPNs) on peach is needed for a longer period of time than is typically afforded by pre-plant fumigant nematicides. Two post-plant nematicides, spirotetramat and fluensulfone, were evaluated for control of and under laboratory and greenhouse conditions. In vitro assays were conducted to test the effect of spirotetramat at 0.

Efficacy of Various Application Methods of Fluensulfone for Managing Root-knot Nematodes in Vegetables.

Fluensulfone is a new nematicide in the flouroalkenyl chemical group. A field experiment was conducted in 2012 and 2013 to evaluate the efficacy of various application methods of fluensulfone for control of Meloidogyne spp. in cucumber (Cucumis sativus).

Efficacy of Fluensulfone in a Tomato-Cucumber Double Cropping System.

Vegetable crops in the southeastern United States are commonly grown on plastic mulch with two crop cycles produced on a single mulch application. Field trials were conducted in 2013 and 2014 in two locations to evaluate the efficacy of fluensulfone for controlling Meloidogyne spp. when applied through drip irrigation to cucumber in a tomato-cucumber double-cropping system.

Chemotaxis disruption in Pratylenchus scribneri by tall fescue root extracts and alkaloids.

Tall fescue (Festuca arundinacea) forms a symbiotic relationship with the clavicipitalean fungal endophyte Neotyphodium coenophialum. Endophyte-infected grass is tolerant to nematode, but the factors responsible are unknown. One objective of this work was to determine if root extracts of tall fescue effected chemoreceptor activity of Pratylenchus scribneri by using an in vitro chemoreception bioassay.
