Preventing Soil-Borne Diseases

Destructive pests such as nematodes, fungi, insects, weeds, and other pathogens can be devastating to a crop. Many common soil-borne issues can be managed with fumigation.

Common Soil-Borne Pathogens

1

FUNGI

The most common soil-borne pathogens. While not all fungi cause plant problems, over 8,000 species do. Most plants are susceptible to some type of fungus.

2

BACTERIA

Examples include Erwinia (soft rot), Rhizomonas (corky root of lettuce), Streptomyces (potato scab, soft rot of sweet potatoes), and Agrobacterium (crown gall).

NEMATODES

Phytopathogenic nematodes are microscopic unsegmented worms. They are especially problematic for root crops, like carrots, but they can affect many types of crops, from ornamentals to orchard trees. Root knot nematodes cause distortion and swelling of roots and can affect the plant's vigor. Needle nematodes feed on the tips of roots, causing branching and swelling. Stubby root nematodes cause short, stubby roots. There are many more types of pathogenic nematodes, including lesion, cyst, dagger, burrowing, reinform, sting, and spiral.
