Fig. 2.

Effects of silver nanoparticles (AgNP) and a commercial preparation of Bacillus firmus (Nortica) on turf quality (line graph), and seasonal fluctuation of Meloidogyne graminis J2 (bar graph) in a bermudagrass putting green. Turf quality was rated on a scale of 1 to 9 with 6 = acceptable and 9 = the best. In the bar graph, J2 numbers are monthly averages per plot collected from all treatments and nontreated control, and the same letters indicates that the average nematode numbers are not different according to Fisher’s least significant difference at P ≤ 0.05. Monthly averages of air temperature are presented. No data of nematode counts in October 2013.
