Pea plants are very vulnerable to diseases. I am doing this experiment to see what kinds of diseases are most common in Pea plants, and what they are most effected by.
Peas are small, green vegetables. They belong to the family of Legumes. Peas are very vulnerable to disease and viruses. Pea plants can grow up to 6 feet tall. In order for peas to grow, they need rich soil, constant moisture, and a cool growing season. There are two types of peas, the Field Pea and the Garden Pea. Field Peas, Pisum Sativum variety Arvense, has smooth hard seeds. They can be many different colors, Green, Yellow, White, Gray, Blue, Brown, or Spotted. Garden peas, Pisum Sativum, usually have Green wrinkled seeds.
Soil is a dirt substance. It is made of many different minerals, like Sands, Silts, Iron and many others. Organisms and animal compost are also found in soil. Plants and all sorts of animals live in soil, along with millions of microscopic organisms. Soil is the key to any sort of plant growth.
APHANOMYCES ROOT ROT
Aphanomyces root rot is a fungal disease often found in Peas, and many other plants. It effects the roots of the plant. When a plant is infected by aphanomyces root rot, the roots change their color and the pea plant produces peas of less quality.
The nematode is a worm that is usually too small to see with the naked eye. They have a small needle ? like mouth that they use to puncture the stem or roots of a plant. This is how many diseases get into plants. By entering through the puncture made by the nematode.
Rhizoctonia root rot is a fungal disease that can be found in many plants. It effects the roots of the plants, and part basal stems. The disease turns the roots and stem of the plant a reddish brown color. The disease is caused by Rhizoctonia solani.
Fusarium wilt is a fungal disease found in many plants. The disease gives the stem and leaves of the plant a yellow or brown discoloration. The fungas can live in a field for many years, and can be spread between fields by farm equipment.
Peas are vegetables that are used a lot in cooking. Though peas are small, they are vulnerable to diseases and need good soil to grow. It is good for farmers to know what the worst and most common diseases in peas are.
