|Bare spots will start to develop due to Race 4 Fusarium issues.|

“In seedlings and young plants, cotyledons and leaves wilt, may turn necrotic, and even fall off the plant, resulting in bare stems. Seedlings of susceptible Pima varieties often die and resemble plant losses caused by damping-off fungi. In mildly affected plants, lower leaves develop symptoms but plants survive, but with reduced vigor and noticeable stunting. Certain strains of the causal fungus only cause symptoms when plants are also infected with the root knot nematode. In those cases, galls are usually prevalent on lateral roots.”
Field scout Damien Jelen hasn’t seen evidence of bare spots in the fledgling cotton fields – so far. In the coming week, he will be visiting more fields to assess stand development and give us a better idea how the crop is faring so far this season.
