“…Such characteristics concur with observations by Monda et al (2001), and have been quantitatively described in other pathosystems (e.g. Kaizer and Lukezic, 1966;Eversmeyer and Burleigh, 1968;Van Hees-Boukema and Zadoks, 1986;Becker and Burr, 1994), but have not been quantitatively documented in the case of ALS.…”

In this review, available knowledge on angular leaf spot (ALS) of bean, caused by Phaeoisariopsis griseola, is analysed and synthesised. This is done through a systems-analytical approach, and successive flowcharts of the system, in order to identify knowledge gaps and guide further research. Six connected sub-models of the ALS monocycle are used as a framework: lesion establishment, lesion extension, defoliation, sporulation, spore liberation, and spore deposition. Each of the sub-models enables the linking of processes to various effects of environmental (physical and host) factors. Disease-induced defoliation is one feature of the pathosystem, leading to a depletion of infectious tissues from the canopy, which are transferred to the ground. Consequences of defoliation may include: strong reductions of the amount of inoculum and of vacant sites in the canopy, limited maximum disease severity, and progressive accumulation of inoculum below the canopy, which may become important a later stage of disease epidemics. These elements are hypothesised to explain the typical behaviour of ALS epidemics in the field, especially late onset, high apparent rate of disease increase, and low level of terminal disease severity in the standing canopy. Epidemiological consequences of lesion expansion, sporulation, and survival of spores deposited onto the canopy are other knowledge gaps in this pathosystem.

“…The application of previously germinated B. bassiana conidia against silverleaf whitefly, Bemisia argentifolii, increased their mortality 2.5 times, in comparison with non-germinated conidia (James, 2001). However, germinated conidia of some phytopathogenic and entomopathogenic fungi, including M. anisopliae, have decreased tolerance to environmental stresses as early as a few hours after germination (Becker and Burr, 1994;Braga et al, 2001).…”

“…Also, conidia oí F oieaginum and V. pyrina were affected by dryness. On the contrary, Becker and Burr (1) reported that, in the case of V. inaequaiis, the viability of ungerminated conidia was not affected by exposure to a dry period of less than 24 h, regardless of the RH level (60 and >90%), and decreased only slightly after 96 h of dryness. In the case of V. pyrina, no lesions developed when inoculated leaves remained dry for more than 12 h at RH <70% (36).…”
