asiaticus ) ( Layden, 2006 ). Growing peaches in a M. mayaguensis -infested site may present a potential problem when trying to establish a new peach orchard, especially if peach is a good host to this new nematode pathogen in Florida. Root-knot nematodes

( Nagel et al., 2008 ). Host response. The response of transgenic plum lines to the ring nematode, Mesocriconema xenoplax , was evaluated in an air-conditioned greenhouse (25 ± 5 °C) at the USDA-ARS, Southeastern Fruit & Tree Nut Research

United States (in Texas) in 2004. To date, CMBS infestations have been reported in at least 17 states in the United States (EDDMapS., 2021). According to previous records, plant species from at least 22 genera (15 families) have been listed as CMBS hosts

that can be incorporated into a red raspberry cultivar of commercial quality. The objective of the experiment described here was to determine the host status of Rubus species and hybrids to P. penetrans . Materials and Methods Accessions of Rubus

not sprayed after planting. Although mild prochloraz phytotoxicity was observed, crop yield does not appear to be affected and fungicide-tolerant or resistant strains of C. acutatum have not yet been reported ( Freeman et al., 1997 ). HOST

Cucurbit downy mildew caused by the oomycete Pseudoperonospora cubensis is economically the most important disease of cucumber ( Cucumis sativus L.) ( Palti and Cohen, 1980 ). Studies on the host range of P. cubensis indicate that ≈20 genera

is known to damage more than 50 plant species, including corn, sorghum, cotton, rice, and bermudagrass ( Luginbill, 1928 ). Multiple overlapping generations of S. frugiperda occur within 1 year and infest several host species. Resistance to older

States ( Wu et al., 2021 ; Xie et al., 2020 ). The more plants beyond the loosestrife family (Lythraceae) and rose family (Rosaceae) to test, the more insights into the relationship between host suitability levels and host classification to obtain, which

particularly vulnerable to this disease due to the frequent occurrence of environmental conditions that are conducive to infection. Spores need several hours of water on the surface of a susceptible rose host for infection to occur (i.e., common with rain and

development of fungicide resistance likely requires a multilayer system for the host to maintain Botrytis resistance. Vitis vinifera , the cultivated grape species grown for its high-quality berries, is highly susceptible to Botrytis . Resistance to
