Oedema (edema) or intumescences are lesions that can occur on begonia, ivy geraniums, cactus, cleome, ivy, ornamental sweet potato vine, and annual thunbergia. Broccoli, cabbage, cauliflower, and tomato can also suffer from this disorder. Houseplants with fleshy leaves, such as jade, peperomia and schefflera, may be prone to edema when the environmental conditions are favorable. The target audience of this factsheet is commercial greenhouse growers.

Intumescences is an abiotic disorder that can affect greenhouse-grown tomatoes. It is a physiological disorder, not an infectious disease. It is also known as edema (oedema). The target audience of this fact sheet is commercial greenhouse growers.

Downy mildew on basil was first reported in the United States in 2007, in Florida. By 2008 and 2009, it was widespread in the Northeast. Downy mildew on basil is seed-borne, so infections can begin in the greenhouse. It is also readily spread by air-blown spores. This fact sheet should be of interest to commercial greenhouse growers.

Many of soils throughout Connecticut tend to be more acidic, formed as rocks were ground and deposited by glaciation. The pH of soils cultivated for vegetable growing typically declines (becomes more acidic) gradually from the removal of calcium, magnesium and potassium ions–by leaching and crop uptake–and from the use of acid-forming fertilizers. Testing every year gives a more complete evaluation and is also appropriate when significant changes have been made in the fertilizer program. Reviewing fertilizer labelling is essential.

Both fungus gnats (Bradysia spp.) and shore flies (Scatella stagnalis) occur in the moist environments common in greenhouses. This publication is intended for commercial greenhouse growers.

With temperatures warming as spring approaches each year, many farmers are deep in preparations for the coming season; crop planning, purchasing seed, prepping nurseries, repairing machinery and more. In the midst of this planning one might look over the farm on a sunny day, and wonder, “What am I going to do with all this over-wintered rye cover crop?”

Garlic is a staple crop in the Northeast, but it can be difficult to know exactly when to plant and harvest garlic in this region. There are quite a few important guidelines during all stages of garlic cultivation.

It’s best not to wait until just before you start your spring seedlings, to begin cleaning, removing clutter and organizing your greenhouses.

Fireblight is often one of the top concerns for Connecticut fruit producers. This disease, caused by the bacterium Erwinia amylovora, is both highly destructive and infectious, making informed disease management efforts a top priority.
