The distribution of disease has been variable throughout the state, owing to the scattered nature of rain and thunderstorms this season.<\/span><\/p>\n<p><span style=\"font-size: 20px\">Thanks to Ann Hazelrigg of the UVM Plant Diagnostic Clinic, we have quite bit of important disease notes to consider:<\/span><\/p>\n<ul>\n<li><span style=\"font-size: 20px\">As has been communicated several weeks ago, <a href=\"https:\/\/www.vegetables.cornell.edu\/pest-management\/disease-factsheets\/basil-downy-mildew\/\">Basil Downy Mildew<\/a> seems to be rather prevalent in pockets within the state. This fungal-like pathogen blows in from the south and showed up earlier than usual this year. Top of the leaves look sunburned and undersides look dirty, as if dirt has kicked up from the ground. Resistant cultivars may get the disease later, but they are not immune. Be vigilant and promptly remove any plants that you suspect may have inoculant. Once an outbreak takes hold, there is not much can be done. Also, a reminder that the <a href=\"https:\/\/basil.agpestmonitor.org\/\">Ag Pest Monitoring Site<\/a> for basil is a great resource for identifying, reporting, and managing BDM. \u00a0If you suspect that you are seeing BDM, please send us a message and\/or send a sample to the Plant Diagnostic Clinic here at UVM.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li><span style=\"font-size: 20px\"><a href=\"https:\/\/ag.umass.edu\/vegetable\/fact-sheets\/tomato-leaf-blights\">Tomato leafspot diseases<\/a> (Septoria and Alternaria) are showing up on lower leaves of field tomatoes and outer rows in high tunnels. Cultural controls (e.g staking, drip irrigation, keeping up fertility , etc.) can be effective strategies and may minimize large outbreaks, but a few key fungicide sprays may be warranted mid season to ensure later crops. Dry weather will slow the spread of the disease but with every rain, the fungi will move higher in the plant.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li><span style=\"font-size: 20px\">Though we are yet to hear of any confirmed incidence of cucurbit <a href=\"https:\/\/www.vegetables.cornell.edu\/pest-management\/disease-factsheets\/downy-mildew-of-cucurbits\/\">downy mildew<\/a> in cucumber or melons within Vermont, it is just a matter of time, as it seems to be all around within the region (e.g. MA, NY, CT). This is a very early arrival for DM, in comparison to previous years.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 20px\">In case you missed it, Meg McGrath of Cornell Cooperative Extension, shared the tips below for identifying CDM. Also, check out Meg\u2019s link to biopesticide options <a href=\"https:\/\/www.vegetables.cornell.edu\/ipm\/diseases\/biopesticides\/\">here.<\/a><\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"font-size: 20px\">\u201cBest time to scout crops for CDM is early morning (before 10).\u00a0 Diagnostic is the grayish brown fuzz of the pathogen\u2019s spores produced on the underside of the yellow, usually angular (on cucumber esp) leaf spots.\u00a0 Spores are produced overnight when humid, especially when dewy, and then are released with humidity change in the am.\u00a0 Growers who contacted me were looking at leaves in afternoon when the spores were gone.\u00a0 When spores are not evident, put leaf upside down on damp paper towel in a closed plastic bag overnight.\u00a0 If the spots are due to CDM, fuzz should be evident next morning. \u201c<\/span><\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li><span style=\"font-size: 20px\">There have been reports of bottom rot issues in lettuce due to wet conditions and poor air circulation. This is typically caused by rhizoctonia. Watch watering and weed pressure.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 20px\">A couple important insect pest notes:<\/span><\/p>\n<ul>\n<li><span style=\"font-size: 20px\">With the recent hot dry spell, <a href=\"https:\/\/ag.umass.edu\/vegetable\/fact-sheets\/thrips-onion\">onion thrips<\/a> have begun to take off on several of the farms that we have been monitoring. Typically, consistent rains help to wash the leaf tubes and knock back thrips populations. Overhead watering can mimic this effect and suppress thrips pressure. There is also some evidence that metallic mulch may delay or deter thrips from colonizing allium plantings.<\/span><\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li><span style=\"font-size: 20px\">We are beginning to see the second flight of <a href=\"https:\/\/ag.umass.edu\/vegetable\/fact-sheets\/leafminer-beet-spinach#:~:text=Spinach%20leaf%20miner%2C%20typically%20an,like%20lamb's%20quarters%20and%20pigweed.\">beet\/spinach leaf miner<\/a> within the region. This is a bit earlier from what we experienced the last couple of years. These leaf miners can cause significant marketable damage to chard, beet greens, and spinach. You can check crops for recent infestations, by looking on the undersides of leaves for their conspicuous white eggs. Weed control, especially for common SLM host plants like lamb\u2019s quarter, can play a key role in reducing the likelihood of an outbreak.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-size: 20px\">As always you can find more details on other pests and diseases at our <a href=\"https:\/\/blog.uvm.edu\/vepart-scouting\/\">pest and scouting website<\/a>.<\/span><\/p>\n<p><span style=\"font-size: 20px\">Thanks to all of the growers that have reached out with there own questions and pest scouting information.
