Abstract
Thymus vulgaris L. is found all over the world and is cultivated in several countries. It is considered an important medicinal plant with anti-inflammatory and aromatic properties. Its cultivation can suffer from infestation by numerous pathogens, which contributes to lower production. Thus, in 2020, a nematological survey in a vegetable growing area in Jaboticabal, São Paulo, Brazil, detected the presence of galls on the root, indicating that it was Meloidogyne spp. To identify the species, a sample with soil and roots was sent to the laboratory. After the analyzes performed, the species was identified as Meloidogyne javanica. This result was based on the morphological characteristics of the adults and the genetic identification. In the morphological part, the following characteristics were found: Perineal region of females low trapezoidal dorsal arch with two lines in laterals, while males have broader basal nodules with a non-raised labial disk, with the head region not separated from the body. Molecular confirmation was performed by genetic sequencing and sequence characterized amplified regions technique (SCAR). This is the first report of T. vulgaris as a host for M. javanica confirmed by Koch's postulate and several lines of evidence. Based on this report, farmers wishing to grow this vegetable should be aware of plants that are also hosts for this species.
期刊介绍:
The Editors of Crop Protection especially welcome papers describing an interdisciplinary approach showing how different control strategies can be integrated into practical pest management programs, covering high and low input agricultural systems worldwide. Crop Protection particularly emphasizes the practical aspects of control in the field and for protected crops, and includes work which may lead in the near future to more effective control. The journal does not duplicate the many existing excellent biological science journals, which deal mainly with the more fundamental aspects of plant pathology, applied zoology and weed science. Crop Protection covers all practical aspects of pest, disease and weed control, including the following topics:
-Abiotic damage-
Agronomic control methods-
Assessment of pest and disease damage-
Molecular methods for the detection and assessment of pests and diseases-
Biological control-
Biorational pesticides-
Control of animal pests of world crops-
Control of diseases of crop plants caused by microorganisms-
Control of weeds and integrated management-
Economic considerations-
Effects of plant growth regulators-
Environmental benefits of reduced pesticide use-
Environmental effects of pesticides-
Epidemiology of pests and diseases in relation to control-
GM Crops, and genetic engineering applications-
Importance and control of postharvest crop losses-
Integrated control-
Interrelationships and compatibility among different control strategies-
Invasive species as they relate to implications for crop protection-
Pesticide application methods-
Pest management-
Phytobiomes for pest and disease control-
Resistance management-
Sampling and monitoring schemes for diseases, nematodes, pests and weeds.
