Recent progress in strawberry disease research.
The recent research on diseases and other pests of strawberry is reviewed. Of over 860 papers published during 1991-95 on all aspects of strawberry research, >22% dealt with diseases, 6% with mites and insects, and <1% with nematodes. Among the disease research papers, those with emphasis on anthracnose (Colletotrichum spp.) were nearly twice as numerous as those on red stele (Phytophthora fragariae), Phytophthora crown rot [P. cactorum] or Botrytis fruit rot [B. cinerea] and their pathogens. The emphasis on these diseases is worldwide, while for some, such as Alternaria black spot (A. alternata), black root rot and Fusarium wilt [F. oxysporum f.sp. fragariae], the importance is regional. A few diseases, such as bacterial angular leafspot (Xanthomonas fragariae), Pseudomonas wilt [Ralstonia solanacearum] and Fusarium wilt, have not received as much attention, except locally, but have the capability of causing much damage on a broader scale in the future.
