The infection rates were found to be higher in irrigated areas than in rainfed lowlands, both when analyzing all observed symptoms together (any of the four diseases) and when specifically considering each of the two diseases BLS and rice leaf blast. Brown spot was particularly prevalent in all six study sites, while yellow mottle disease was particularly structured geographically. Various diseases were frequently found together in the same field (co-occurrence) or even on the same plant (coinfection), especially in irrigated areas.Tomato (Solanum lycopersicum L.) is one of the common and important economic crops in Taiwan. In July 2018, tomato leaves with unusual yellowing and lesions were observed in Taichung, Changhua, Nantou, and Yunlin counties in Taiwan. Symptomatic leaves initially showed chlorotic, irregularly shaped patches on adaxial side of leaves; and days later, necrosis appeared in the patches center. The disease incidence was 4 to 25% and occurred mostly on large type tomato in the field and greenhouse while rarely on cherry tomato. Since the pathogen could not be cultured in potato dextrose agar, for initial pathogen observation, symptomatic leaves were examined directly under light microscope. Conidiophores were found emerged through abaxial stomata of the lesion, and were erect, single and sometimes branched, with single-celled and dimorphic conidia, suggesting the lesions were associated with a powdery mildew. The white to hyaline pathogens collecting directly from fresh signs were also examined. Primary conidia were ers (Capsicum annuum L.), which has been also reported as a host of L. taurica (Tzen et al. 2019), suggesting these two crops could be as alternate hosts of L. taurica in the field. Cross-species infection should be taken into consideration while managing the disease.Beans are the most cultivated legume in the world. In Mexico, it is the second most important crop after corn (FAO 2020; SIAP 2020). Bean plants "Flor de Mayo M38" variety were affected by a foliar disease during the agricultural cycle 2019 in Puebla-Mexico (19°02'46.6" LN and 98°05'15.6" LO). Necrotic V- shaped lesions were observed on the margins of the leaves surrounded by yellow halos followed by foliar necrosis, affecting 40% of the crop. In Mexico this variety of cultivars is in great demand for local consumption and generates income in foreign currency (Castellanos et al. 1997). Sampling was carried out on 50 plants "Flor de Mayo M38" variety, with necrotic leaf symptoms from ten plots of one hectare. Samples were cut into pieces (5 mm), disinfested with 1% hypochlorite 3 min, and washed with sterile distilled water. Subsequently, samples were dried on sterile paper and placed on Petri plates containing yeast extract calcium carbonate dextrose agar (YDC) medium and kept at 36°C for 3 days. Colonies of mptoms observed in the field. Koch's postulates were confirmed by the reisolation of Xcf1-APJR strain, which presented the same colony morphology, partial sequence, and polyclonal specific detection. This is the first report of this pathogen causing necrotic leaf spot in beans from the "Flor de Mayo M38" variety in Puebla-Mexico. The author(s) declare no conflict of interest.

Based on six pea differentials previously used to differentiate 11 pathotypes in France, pathotypes were identified among field isolates from Saskatchewan (14) and Alberta (18). Four isolates from the USA and standard isolates for pathotypes I and III designated in the French study were also included. Each isolate was tested twice in replicated experiments by inoculating French pea differentials Baccara, Capella, MN 313, 902131, 552 and PI 80693, along with the Canadian susceptible pea cultivar CDC Meadow and partially resistant USDA line PI 660736 under controlled conditions. Pea plants grown in vermiculite were inoculated 10 days after seeding by pipetting 5 mL of a suspension containing 1 x 103 zoospores mL-1 to the base of each plant. Root discoloration was scored 10 days post-inoculation using a 0-5 scale. Testing revealed that 38 of the isolates, including standard pathotype I isolate RB84 belonged to pathotype I, 4 isolates including standard pathotype III isolate Ae109 were pathotype III, and USA isolate Ae16-01 was a pathotype II isolate. An alfalfa isolate from Quebec was avirulent on all pea genotypes. These findings indicate that pathotype type I is predominant on the Canadian prairies.Date palm (Phoenix dactylifera L.) is one of the world's oldest cultivated fruit crops. find more In Jordan, date palm farming started in the 1990s. The major date palm planting areas are Jordan valley, Aqaba, and Azraq (Al Antary et al., 2015). 'Medjool' and 'Barhi' are the two major cultivars in Jordan. In early 2018, some 18- to 24- month old date palm trees (cv 'Medjool') showed light brownish discoloration and dryness symptoms on the leaves and branches of infected date palm trees at the Jordan University Agricultural Research Station (JUARS) at the Jordan Valley (GPS coordinates 32.086871, 35.597219) (Figure 1). All the leaf parts including leaf base, spines, and leaflets were wrinkled and malformed. The infection led to a loss of 1-2% out of 1100 total Medjool trees at the station. Similar symptoms were observed in many date palm farms in the Jordan Valley. Diseased samples from rachis tissue from the JUARS were collected, surface sterilized with 5% sodium hypochlorite for five minutes, rinsed with distilled water for three times, dried, and plated on potato dextrose agar (PDA) medium (HIMEDIA).
