Abstract: N.sup.1 -methoxycarbonyl-N.sup.1 -alkyl-3,5-dinitro-N.sup.4,N.sup.4 -dialkylsulfanilamides are useful as pre-emergence herbicides for crabgrass, with essentially no herbicidal effects on lawn grasses such as ryegrass and dichondra.

Abstract: A process for applying a pesticidal composition to granular vegetative products such as grains and seeds, which comprises:1. loading and compacting a granular material into a first chamber by conveying it upwardly against the force of gravity;2. conveying and tumbling the compacted granular material from the first chamber into a second chamber of greater capacity than the first chamber to permit mixing and tumbling of the granular material;3. spraying the tumbling granular material with a pesticidal composition in the second chamber; and4. discharging the sprayed granular material from the second chamber.Apparatus suitable for carrying out the process of the invention are also described.

Abstract: Effective inhibition of the ultraviolet degradation of a poly-1-olefin is accomplished by the incorporation of a certain finely divided metallic nickel into the polymer.
