Late blight on potatoes More late blight information Large leaf spots (lesions) are common with late blight. These were the main symptom seen in a commercial field on LI in 2009 when this disease was first found. Upper leaf surface with late blight lesions (below) Spores of the pathogen are visible on the lower (under) surface of leaves (below) Close up of spores (below) Leaf lesions can be small when they first start to develop (below left). Symptoms also occur on other parts of potato plants including stems, petioles, and flowers.

Get Started or Expert Advice and Resources Vegetable Diseases Cornell Home Page Detection of Potato Tuber Diseases & Defects fact sheet Introduction Good disease management is critical to the successful production of the white potato (Solanum tuberosum L.). The potato plant is susceptible to at least 75 diseases and nonparasitic disorders, many of which consistently cause yield losses in potato production areas in the northeastern United States. Potatoes are a vegetatively propagated crop, and potato seed tubers can be an important source of disease inoculum. Several types of injury that can influence plant vigor and subsequent yields also occur on seed tubers. The objective of this bulletin is to aid in the diagnosis of those tuber diseases and defects that most often result in production problems. The Why, When, and How of Potato Seed Evaluation Why. When. How. External. Internal: Five of these disorders usually produce no diagnostic symptoms on the exterior of the tuber, and diagnosis must be based solely on internal symptoms.

Garlic Gardening I haven't purchased garlic since 1996. That's because I grow enough to eat a bulb of garlic every day, year-round. While most of my garden adventures are hobby-level attempts at self-sufficiency, my garlic crop is for real. Garlic is an overwintering crop, planted in fall and harvested mid-summer. A year's supply of garlic hanging in your garage hints at many great meals to come, but by the time you reach that milestone the rewards have already been flowing for months. As spring continues, your plants will continue to skyrocket, and in late May—assuming you planted a flowering variety—you'll be treated to a funky display of garlic blossoms curling from the plant tops. The flowering varieties of garlic are collectively called hardnecks, so named because of their woody flowering stalks. The first step in growing your own garlic stash is getting your paws on some good garlic for planting. In my case, x = 365/(5-1), or 91.25, which I round up to 92. Ask Ari: Got milk options?

Tomato Leaf Spots - Is it Late Blight, Early Blight, or Septoria Leaf Spot? Is it Early Blight, Late Blight, or Septoria?: Early Blight: If you are dealing with Early Blight, the tomato leaves will have one or two spots per leaf, approximately ¼ to ½ inch in diameter. There is no treatment for early blight. Late Blight: If your tomatoes have late blight, you will see spots that start out pale green, usually near the edges of tips of foliage, and turn brown to purplish-black. As with early blight, the method for dealing with late blight is to pull and destroy the plants, look for resistant varieties, and plant in a different part of the garden next year. Septoria Leaf Spot: Septoria leaf spot is aptly named, because the primary symptom of the disease is that numerous brown spots appear on the leaves, approximately 1/16 to 1/8 inch in diameter. If your tomatoes are infected, they will keep producing fruit.
Making Comfrey Compost, Comfrey Liquid Feed or Tea Comfrey as a Compost Activator Cuts of comfrey fresh or wilted can be laid onto the compost here, layered with the weeds or grass cuttings. Comfrey is so rich that it can be used as if it was manure to activate a slow compost heap. A layer of wilted comfrey can be laid in the trench before planting potatoes. Wilted comfrey can also be laid between the rows when potatoes are growing. Adding layers of cut comfrey to a leafmould pile will add some nutrient value to the leafmould which is useful when making your own seed composts.
