“…Similar decrease of disease control level was also observed for other concentrations of trifloxystrobin applied (Veloukas et al, 2007). Fluazinam and boscalid applied two days after inoculation of peanut plants with Scleortinia minor reduced disease incidence, but no reduction was recorded when these fungicides were applied four days after the inoculation (Smith et al, 2008). Applied one and three days after inoculation of cucumber plants with Pseudoperonospora cubensis, dimetomorph gave 67 and 32 % disease control, respectively, while the efficacy of azoxystrobin decreased from 96 % when applied one day after inoculation to 39 % when applied three days after inoculation (Wang et al, 2009).…”

“…Significant yield increases were reported with the use of these fungicides, indicating their effectiveness in the control of fungal diseases [53,54]. Since Complex II is a common enzyme complex system existing in many eukaryotic and prokaryotic organisms [26], nontarget effects of Complex II inhibitors on soil bacteria were repeatedly reported [55,56], suggesting that cautions must be used with these chemicals.…”

Fungicide: Modes of Action and Possible Impact on Nontarget Microorganisms

Fungicides have been used widely in order to control fungal diseases and increase crop production. However, the effects of fungicides on microorganisms other than fungi remain unclear. The modes of action of fungicides were never well classified and presented, making difficult to estimate their possible nontarget effects. In this paper, the action modes and effects of fungicides targeting cell membrane components, protein synthesis, signal transduction, respiration, cell mitosis, and nucleic acid synthesis were classified, and their effects on nontarget microorganisms were reviewed. Modes of action and potential non-target effects on soil microorganisms should be considered in the selection of fungicide in order to protect the biological functions of soil and optimize the benefits derived from fungicide use in agricultural systems.

“…Sanitation practices are directed at limiting the spread of the fungus by preventing its introduction into new fields. The fungicides fluazinam and boscalid provide good disease control when applied preven-tively or at the first sign of disease (9,10,34). However, the cost per application of these fungicides ranges from $100 to $150/ha depending on the rate used.…”

In 2001, entries from the peanut core collection, a subset of the USDA peanut germplasm collection, were planted in non-replicated plots in a field with a history of Sclerotinia blight caused by Sclerotinia minor. Variability existed among entries for reaction to Sclerotinia blight. Of the 744 entries evaluated, 11% had no disease, nearly 30% had ,10% disease incidence, and only 21% had 50% disease incidence or more. Most of the resistant entries had an upright growth habit and were in early and mid-maturity groups. Many of the early maturing entries were susceptible to the foliar disease pepper spot which occurred throughout the study. Entries were selected for further evaluation in replicated plots based on a nil to low (,10% 208, 128, 804, 582, and 273 combined resistance to Sclerotinia blight, pepper spot, and web blotch with less than erect growth habits. Entry 103 had good Sclerotinia blight resistance and yield, but an upright growth habit. Entry 92 had an upright growth habit and low yield, but good Sclerotinia blight resistance. Entries 92 and 103 had upright growth habits but were among the best entries for resistant to pepper spot and web blotch. Entries 426, 184, and 562 were upright and susceptible to pepper spot, but had resistance to web blotch and the best resistance to Sclerotinia blight. These entries appear to be useful sources of resistance to Sclerotinia blight for breeding programs and for increasing the probability of finding additional sources of resistance in clusters of germplasm identified within the entire USDA collection.
