Fig. 2. Effect of various adjuvants on the bioherbicidal efficacy of Phomopsis amaranthicola. The adjuvants tested were: IE=invert emulsion, META=Metamucil, KEL=Kelzan, WAT=water, SIL=Silwet L-77, TWN= Tween 20, TRI=Triton X-100, NAT=Natrasol, and KELG=Kelgin. Efficacy was measured in terms of proportion of dead Amaranthus hybridus plants. Graph shows data from three trials (gray bars show the effect of conidia + adjuvant and black bars show the effect of the adjuvant alone). Bars with the same letters are not significantly different from each other at P = 0.05, as determined by Duncan's Multiple Range test. From Rosskopf et al (94).
