Affected plants show stunted root development, swollen root tips, chlorosis and whitening of lower leaves, leaf tip burn, and stunted growth. The chloroacetamides kill germinating seedlings, not established plants. Triazines Key performance features. Atrazine, Bladex, Evik, Milogard, Igran, Sencore, Lexone. Atrazine, Bladex, Evik, Igran.
Sunlight plays a minor role in triazine losses.
Should the active ingredient stay unprotected on the soil surface, a relatively small portion may be lost due to ultraviolet degradation. Water and soil pH are very important. Triazine activity is largely determined by soil clay and organic matter. Greater clay and organic matter require a higher dose. These herbicides have plant-back restrictions, which vary with region and crop species.
