The stubby root nematode is a plant pathogenic nematode. They are usually most successful in sandy soils and are capable of considerable vertical migration between the surface and depths greater than 1m (3ft). The life cycle is completed in as short as 2½ weeks at 30°C (86°F), but at cooler temperatures may take as long as 6 weeks.[1]
Symptoms[edit | edit source]
Damage caused by P. minor usually occurs in irregularly shaped patches within a given field. Symptoms are usually more severe in sandy than in heavier soils. Above ground symptoms include; stunting, poor stand, wilting, nutrient deficiency, sensitivity to drought[2][3] and lodging. Roots may appear abbreviated or "stubby" looking. However, all these symptoms can be caused by other factors.[4]
Control[edit | edit source]
Chemical[edit | edit source]
Due to the depth at which P. minor lives, standard fumigants are ineffective. This combined with data showing that populations often rebound to greater numbers following the use of fumigants renders their use redundant.[4]
