Molybdenum, applications

Molybdenum application, especially at higher rates (sodium molybdate at 10.1 kgha" ), was shown to decrease the activity of polyphenol (catechol) oxidase and the contents of total phenolic com-... 

Like other micronutrients. Mo has been found to influence the incidence of plant diseases. Molybdenum application has been reported to decrease leaf-spot infection caused by Septoria sojina in soybeans (Girenko, 1975) and to decrease Verticillium wilt in tomatoes (Dutta and Bremner, 1981) and cotton (Gossypium spp.) (Miller and Becker, 1983). It also reduces the production of roridin E toxin by Myrothecium roridum (Fernando, Jarvis, and Bean, 1986) and zoosporangia formation by Phytophthora spp. (Halsall, 1977). Haque and Mukhopadhyay (1983) observed that soil application of Mo caused some reduction in the population of parasitic nematodes. Whether these effects are due to some specific role of Mo in plant disease resistance or are indirect effects of Mo through plant metabolism is not certain.

Parker and Harris (1962) reported that soybean yields on some soils in Georgia were not affected by lime applications when Mo was also applied. In contrast, Giddens and Perkins (1972) showed that lime alone did not increase the available Mo to amounts that would be adequate for alfalfa production on highly oxidized soils of the Georgia piedmont (pH 5.8-6.0). Molybdenum applications (llOgha" ) were needed to maintain the alfalfa stands.
