Integrated pest management, in which the conventional pesticides are augmented by one or more nonchemical control practices, has been receiving renewed interest. What is new in this revitalization of an old technique is the careful and more knowledgeable application of a variety of control techniques.

p-Bromoaniline is rapidly acetylated by four soil microorganisms. Two fungal species convert metobromuron to p-bromoacetanilide, but a bacterial and an algal species do not metabolize metobromuron. Acetylation may serve as a detoxification mechanism by competing with azobenzene formation in utilizing the aniline formed by metabolism of substituted urea herbicides.

The radiorespirometric method was used to study the pathways of glucose metabolism in the rough and smooth variants of Bacillus stearothermophilus NCA 1518. The Embden-Meyerhof (EM) pathway was more active in the smooth variant than in the rough variant. The participation of the hexose monophosphate shunt (HMP) and EM pathways in the smooth variant was calculated as 4.2 and 95.8%, respectively. The rough variant utilized glucose via the EM pathway exclusively or in combination with a pathway other than the HMP pathway. The estimated efficiency of the tricarboxylic acid system in the rough and smooth variants was 81.3 and 4.9%, respectively.
