There are three ways of managing Heterobasidion annosum: silvicultural control measures, chemical methods and biological control. Silvicultural control involves planting species with low susceptibility. This could lower the root rot problem and free an infected site from inoculum. A more extreme measure is to remove the inoculum from the ...
Armillaria root rot is a fungal root rot caused by several different members of the genus Armillaria. The symptoms are variable depending on the host infected, ranging from stunted leaves to chlorotic needles and dieback of twigs and branches. However, all infected hosts display symptoms characteristic of being infected by a white rotting ...
Root rot is a condition in which anoxic conditions in the soil or potting media around the roots of a plant cause them to rot. This occurs due to excessive standing water around the roots. [ 1 ] It is found in both indoor and outdoor plants, although it is more common in indoor plants due to overwatering, heavy potting media, or containers with ...
Trunk injection or endotherapy also known as vegetative endotherapy, [1] [2] [3] is a method of target-precise application of pesticides, [4] [5] [6] plant resistance activators, [7] or fertilizers [8] into the xylem vascular tissue of a tree with the purpose of protecting the tree from pests, or to inject nutrients to correct for nutrient deficiencies.
It may take years for infected trees to show signs of disease, leading to an underestimation of disease prevalence. Studies show that the spread of disease in eucalypt forests is associated with infected stumps left following logging operations. Although several methods have been suggested to control the spread of disease, they are largely ...
Root rot is a common disease of Florida green beans and can reduce crop yields there by up to 75% if untreated. [96] It was not until the 1950s that an effective fungicide was found to control root rot. Trials in Florida in the 1950s showed that applications of PCNB were able to reduce incidence to 3%. [98] PCNB is still the primary treatment ...
Rhizoctonia solani root rot on corn roots, magnified 0.63X. Damping off can be prevented or controlled in several different ways. Sowing seeds in a sterilized growing medium can be effective, although fungal spores may still be introduced to the medium, either on the seeds themselves or after sowing (in water or on the wind).
White root rot has now become the most threatening root disease of the rubber tree in both Asian and African continents, which supply 98% of the natural rubber to the world market. In Indonesia alone, the affected area is more than 80,000 ha. As a whole 5–10% of the cultivated lands are in bare patches due to this deadly disease.
