Cygon injury is expressed initially as marginal leaf rolling, and later as degrees of flecking on the leaves. There is a rate response. Avoid using on small, unhardened plants. Use the low rate on established plants. Enide injury is fairly common.
Initial symptoms are marginal burn and whitish blotched.
Later a brown flecking between the veins appears. Use preplant herbicides where applicable. Be careful and select ideal weather conditions for applying herbicides. A shield on the spray boom is helpful. Mosaic symptoms are common, and are often confused with mutations, nutrient deficiency, or chemical injury.
