Optimizing use of new products for management of root-knot nematode, Meloidogyne incognita, on carrots
Becky Westerdahl - University of California, Davis.
Two field trials evaluated new products for management of root-knot nematode. Products were tested either alone, or in combination with other products. Trials included an untreated control and were conducted in a randomized complete block design with 5 replicates per treatment. Twenty-three treatments in the first trial included: fluopyram (Velum, Bayer); TECA Fulvic, TECA Nemat-X, and TECA Root from IG Agrosolutions; fluensulfone (Nimitz, Adama); fluazaindolizine (Salibro, DuPont); metam potassium (K-pam HL, AMVAC); QL Agri (Quillaja, Desert King); FBS (soil organic acids, Fbsciences); Cedroz (geraniol and thymol, Eastman Chemical Company); and CrossLink (tergatol, amino acids, Beem Biologics). Seventeen treatments in the second trial included: fluensulfone, fluopyram, Paecilomyces lilacinus (BioAct, Bayer); Paecilomyces lilacinus (MeloCon, Certis); fluensulfone; ISO (Guayule extract), SA Propel (soil organic acids), and Focus (bacterial complex) from Beem Biologics; Groactive (Yucca and Quillaja, Desert King); and 1,3-dichloropropene (Telone II, Dow AgroSciences). All products evaluated increased yields compared to the untreated control. Compared to individual products alone, yields increased with combinations of Velum plus TECA products; of QL Agri plus FBS; of K-pam plus Cedroz; of Velum with BioAct, and of ISO with SA Propel.
