Effect of Foliarly Applied Spirotetramat on Reproduction of Heterodera avenae on Wheat Roots

Abstract

The cereal cyst nematode, Heterodera avenae, has the potential to reduce yields of cereal crops in the Pacific Northwest. Spirotetramat (Movento) is a foliar-applied insecticide with ambimobile translocation that reduces fecundity of sucking insects which feed on roots as well as foliage. Spirotetramat (88 g/ha) was applied to foliage during 2010 in two wheat fields infested by H. avenae near St. Anthony, ID and Palouse, WA. In Idaho, two applications at 2-week intervals during late spring to plants already exhibiting swollen white females reduced the postharvest density of H. avenae eggs plus juveniles by 35% (P = 0.03) compared to the nontreated control. In Washington, a single application before white females became apparent reduced the nematode density by 78% (P = 0.01). Grain yields and test weights were not significantly affected by application of spirotetramat at either location. In addition, symptomatic plants from the Idaho field were transplanted into greenhouse pots and treated with spirotetramat. One application (110 g/ha) reduced numbers of eggs plus juveniles/plant by 78% (P = 0.02). Spirotetramat effectively reduced H. avenae populations and warrants further evaluation as a substitute for crop rotations or long fallow periods that reduce nematode population densities in infested fields.

“…Spirotetramat acts as an acetyl-CoA carboxylase inhibitor and is intended for use on a range of agricultural crops. Notably, spirotetramat is active against a broad spectrum of sucking insects (Brück et al, 2009;Kay & Herron, 2010;Kumar, Kuttalam, & Chandrasekaran, 2009;Smiley, Marshall, & Yan, 2011).…”

Influence of Nematicides and Fungicides on Spring Wheat in Fields Infested with Soilborne Pathogens

“…as much as 50% for up to 3 months, and reduced the number of Tylenchulus semipenetrans for 6 weeks. Smiley et al (35) reported that a single applicafion of spirotetramat reduced the postharvest density of H. avenae by 28% in an Idaho field and by 78% in a Washington field but did not improve the yield of spring wheat at either location. In fields infested with low to moderate densities of P. thornei, there were no differences among spirotetramat and control treatments for yield or for postharvest nematode density in spring and winter wheat during 2010 {unpublished data).…”

“…Data from the literature also shows that the use of spirotetramat against nematodes varies. Smiley et al (2011) suggested that applications of this substance reduced the density of Heterodera avenae. In turn, the research of Zasada et al (2010) (2012) showed inefficiency of this product in the controlling of Pratylenchus spp.…”

“…Among the active ingredients of pesticides used for plant protection against different nematodes, the most popular are: oxamyl (Philis 1994;Tu et al 1996), spirotetramat (Smiley et al 2011(Smiley et al , 2012, diazinon (La Mondia 1999;Jagdale and Grewal 2002), carbofuran (Adegbite and Agbaje 2007;Jada et al 2011). Despite the efficacy of chemical substances, nematicides are being increasingly replaced by various eco-friendly biological products.…”
