Persistence of benomyl and captan and their effects on microbial activity in field soils.

چکیده
Fusarium root rot, caused by Fusarium oxysporum schl. f. sp. pini (Hartig) Snyder & Hansen, causes severe losses to some species of conifers even though beds are fumigated with methyl bromide-chloropicrin (3:2) the autumn before spring seeding. Benomyl (methyl-l-(butylcarbamoyl)-2-benzimidazole carbamate) at ll.2 kg a.i./ha or captan (N-trichloromethylthio-4cyclohexene-l,2-dicaboximide) at 7.3 kg a.i./ha were applied to beds of sugar pine (Pinus lambertiana Dougl.) on Central Point sandy loam to control seedling mortality (Cooley 1983), but no measurement was made of its persistence or of its effect on soil microbial activity.

Similar to plants, soil salinity may reduce microbial growth and activities in different ways. The aim of this study was to determine the effects of different levels of salinity on some microbial indices in the presence and absence of plant's living roots. In this study, five levels of salinity using NaCl, CaCl2, MgCl2 and KCl and three soil media (soil with no plant, soil cultivated with wheat...
متن کاملPlant growth-promoting activities of Streptomyces spp. in sorghum and rice
Five strains of Streptomyces (CAI-24, CAI-121, CAI-127, KAI-32 and KAI-90) were earlier reported by us as biological control agents against Fusarium wilt of chickpea caused by Fusarium oxysporum f. sp. ciceri (FOC). In the present study, the Streptomyces were characterized for enzymatic activities, physiological traits and further evaluated in greenhouse and field for their plant growth promoti...

The application of herbicides as organic chemical compounds to control pest and weeds may affect the population and activity of microorganisms, and this may have an influence on biochemical processes that are important for soil fertility and plant growth. The primary objective of this study was to evaluate different loading rates of eradican (EPTC) on soil microbial biomass C and N, microbial b...

Bioassay-guided fractionation of the ethyl acetate extract of Ruta graveolens roots yielded rutacridone epoxide with potent selective algicidal activity towards the 2-methyl-isoborneol (MIB)-producing blue-green alga Oscillatoria perornata, with relatively little effect on the green alga Selenastrum capricornutum. The diol-analog of rutacridone epoxide, gravacridondiol, which was also present i...
