Introduction Panax notoginseng is a precious Chinese medicinal material. Soil fumigation can control soil-borne disease and overcome the continuous cropping obstacles of P. . However, chloropicrin (CP) kill non-target soil microorganisms reduce microbial diversity, but long-time impacts CP on are less reported. Methods We studied long-term effects microbes with high-throughput gene sequencing, ...

The elimination of the ground based nocturnai inversion during the morning hours may be associated with very high surface pollutant concentrations, as elevated plumes fumigate into the developing mixed layer. The common approach of studying this phenomenon is based on the application of Gaussian plume model concepts using prescribed meteorological data. Such a methodology, however, is deficient...

The objectives of this experiment looked at were that the DNA, both skin cells and saliva, have potential binding with superglue as it coats each object being fumed. If DNA has superglue, then is very possible for to be carried in air by humidifier, thus contaminating other objects. For first experiment, two saliva covered microscope slides, one female male, fumed along 25 sterile slides. Each ...

Application of 4-amino-3,5,6-trichloropicolinic acid (picloram) to roots stimulated the production of ethylene in both mesquite [Prosopis juliflora (Swartz) DC. var. glandulosa (Torr.) Cockerell] and huisache [Acacia farnesiana (L.) Willd.] seedlings. Herbicide levels rose in tissues before we detected increased ethylene production. Rates of ethylene production by various parts of the plant par...
