Effects of Paratylenchus projectus on growth of sunflower
Paratylenchus projectus significantly (P<0.05) reduced sunflower seed yields in a greenhouse study. Yield reductions occurred in both fertilized and unfertilized treatments and ranged from 12 to 33 percent. Application of fertilizer did not affect P. projectus damage to sunflower. Populations of P. projectus increased 20- to 126-fold over 14 wk. Population increase of P. projectus on sunflower was highest at 20 and 25C, and populations did not increase above initial inoculum levels at 10, 15, or 35C
