plant pest and disease control Club Root

Club Root

A serious problem in home gardens is that clubroot disease can be managed using these proven, organic methods.

Affecting most brass crops (such as cabbage, broccoli, cauliflower, etc.), clubroot is a serious plant disease in North American home gardens. It is caused by the soil-borne fungus Plasmodiumophora brassica, which infects plants that are easily infected by root hairs. Diseased roots swell, deform, deformed (clubbed) often crack and rot. As a result, plants have difficulty absorbing water and nutrients properly.

During the daytime heat, the plants often grow poorly and wither; Plants are often revived on cold nights. The outer leaves turn yellow, purple, or brown. The club will reduce root yield and cause total crop failure.

Fungal spores can be spread by air, water and garden tools. Disease development can occur at different stages but is preferred due to high humidity, low soil pH, and soil temperature between 64 and 77˚F. Seeds can live in soil for up to 10 years.

Treatment

Fungicides do not treat the microorganisms that live in this soil.

If possible, select resistant crops.

Try to prevent this disease by keeping the garden clean and rotating crops.

Keep in mind that germs can persist in the soil for up to 20 years. If the club has roots, you may want to sunbathe the soil. *

Control vulnerable weeds - mustard, radish, shepherd's purse - this will reduce the chances of infection.

After application, carefully remove the affected plants and disinfect the garden tools (from one part bleach to 4 parts water).

Mix oyster shell or dolomite lime in your garden in the fall and raise the pH of your soil to the high alkalinity of 7.2. There are simple and inexpensive soil testing tools to check the pH frequently.

* To sunbathe your soil, put clear plastic tarp on the soil surface for 4-6 weeks during the warmer part of the year. Soil sunlight can reduce or eliminate many soil-dwelling pests, including nematodes, fungi, insects, weeds and weed seeds.

Garden Plants Lighten Up with These Crisp White and Green Selections

Crisp White and Green Selections That Thrive in the Heat 1. The Rule of Three "Instead of a boxwood or other shrub, you can use containers to anchor a space or garden bed," says landscape designer Carmen Johnston of Bespoke Garden Plans in Thomaston, Georgia. What's the trick to making it work? When choosing your containers, choose three that are the same shape and material — one small, one medium, and one large. She chose 'Cora Cascade Polka Dot' vinca as the base for all the containers. In the second container, she brought in 'White Delight' caladiums and 'Lemon Twist' plectranthus for height. In the largest container, she filled the same plants with 'Kimberly Queen' ferns, 'Peppermint' strap-leaf caladiums, and creeping jennies for warm, summery color. These are low-maintenance choices because, as Johnston says, “they can handle intense heat and full sun.” 2. Garden Type “We don’t need to add flowers to create a beau...
