El cultivo de tomate de cáscara es afectado por la presencia de diversas plagas y enfermedades en donde figura la presencia del psílido Bactericera cockerelli Sulc., al cual se le atribuye el amarillamiento y aborto floral. El control de este psílido no ha sido eficiente por el desconocimiento de la distribución espacial del mismo, por lo tanto, el presente estudio se realizó con la finalidad de conocer la distribución espacial de ninfas de Bactericera cockerelli, en tomate de cáscara por medio de técnicas geoestadísticas. Se determinó el semivariograma experimental y se ajustó a un modelo teórico, el ajuste se validó con el método de validación cruzada y se obtuvieron los mapas de agregación de la plaga a través del krigeado. Los resultados mostraron que las poblaciones de ninfas de Bactericera cockerelli, presentan una distribución del tipo agregada, la cual fue corroborada con los mapas de densidad. La plaga no infestó el 100% de la superficie de las parcelas estudiadas, lo cual nos ayuda a crear programas de manejo eficaces y dirigir las medidas de control a las áreas específicas de infestación.ABSTRACTThe husk tomato crop is affected by the presence of several pests and diseases which includes the presence of Bactericera cockerelli Sulc., psyllid to which, yellowing and floral abortion is attributed. The control of this psyllid has not been efficient; therefore, the present study was carriedout with the purpose to know the spatial distribution of B. cockerelli nymphs, on husk tomato by using geostatistical techniques. The experimental semivariogram was determined and a theoretical model adjusted, and validated with the cross validation method and the aggregation maps of the plate were obtained through krigeado. The results show that the populations of B. cockerelli nymphs exhibits an aggregate type distribution, corroborated with density maps. The pest did not infest 100 % of the plots studied, which helps us to create effective management programs and direct control measures to specific areas of infestation.

Protective Structures

Tomato crops are among the most important vegetables cultivated worldwide, Mexico being one of the major producing countries. Large quantity of this crop is found in states belonging to the arid northwest of the country; the adaptation of these regions to vegetable production has been significant with the support of agricultural technology due to the use of protective structures for plants, such as greenhouses and shaded mesh. However, pests and diseases are a major biotic factor that significantly reduces production. There are more than 200 diseases associated with the nightshade of various etiologies. The process of identifying the cause of a disease in plants is called diagnosis. The diagnosis of plant diseases has been described as an art and a science; it requires scientific knowledge of plant pathology and related disciplines. Effective disease control requires making the best possible decisions to reduce the risk of serious production losses. Control strategies based on prevention of disease and methods that slow the spread of such diseases. Therefore, proper management of diseases affecting the tomato crop, knowledge and understanding of the diagnosis and its infectious cycle is vital and to establish effective control measures.

Abstract L. camara is a highly variable ornamental shrub, native of the neotropics. It has been introduced to most of the tropics and subtropics as a hedge plant and has since been reported as extremely weedy and invasive in many countries. It is generally deleterious to biodiversity and has been reported as an agricultural weed resulting in large economic losses in a number of countries. In addition to this, it increases the risk of fire, is poisonous to livestock and is a host for numerous pests and diseases. L. camara is difficult to control. In Australia, India and South Africa aggressive measures to eradicate L. camara over the last two centuries have been largely unsuccessful, and the invasion trajectory has continued upwards despite control measures. This species has been the target of biological control programmes for over a century, with successful control only being reported in a few instances.

The Impact

Verticillium (Verticillium dahliae Kleb.) wilt is one of the most devastating diseases affecting olive (Olea europaea L. subsp. europaea var. europaea) cultivation. Its effective control strongly relies on integrated management strategies. Olive cultivation systems are experiencing important changes (e.g., high-density orchards, etc.) aiming at improving productivity. The impact of these changes on soil biology and the incidence/severity of olive pests and diseases has not yet been sufficiently evaluated. A comprehensive understanding of the biology of the pathogen and its populations, the epidemiological factors contributing to exacerbating the disease, the underlying mechanisms of tolerance/resistance, and the involvement of the olive-associated microbiota in the tree’s health is needed. This knowledge will be instrumental to developing more effective control measures to confront the disease in regions where the pathogen is present, or to exclude it from V. dahliae-free areas. This review compiles the most recent advances achieved to understand the olive–V. dahliae interaction as well as measures to control the disease. Aspects such as the molecular basis of the host–pathogen interaction, the identification of new biocontrol agents, the implementation of “-omics” approaches to unravel the basis of disease tolerance, and the utilization of remote sensing technology for the early detection of pathogen attacks are highlighted.

The Cost

The study was conducted in Khowai district of Tripura with randomly selected True Potato Seed (TPS) growers. TPS can serve as a great alternative to the seed tubers in the hilly state of Tripura as only 100 g TPS is needed for one ha. of land as compared to nearly 2 tones of seed tubers required to plant in the same area. TPS can be used as a suitable alternative technology of potato cultivation in the state to improve the productivity and reduce the cost of production. The technological need of the majority of the TPS growers, i.e., 87.50 per cent was plant protection measures with rank I. The other technological need observed were post harvest treatment (79.17 %) which includes application of boric acid, sorting and grading, packing, curing etc. and method of fertilizer application (76.67 %) with II and III rank respectively. So, it is utmost necessary that the agricultural extension workers through regular trainings on plant protection measures with the TPS growers should guide the farmers to get optimum yield per unit area by effective management of pests and diseases.

The Stability

The length of time Potato spindle tuber viroid (PSTVd) remained infective in extracted tomato leaf sap on common surfaces and the effectiveness of disinfectants against it were investigated. When sap from PSTVd-infected tomato leaves was applied to eight common surfaces (cotton, wood, rubber tire, leather, metal, plastic, human skin, and string) and left for various periods of time (5 min to 24 h) before rehydrating the surface and rubbing onto healthy tomato plants, PSTVd remained infective for 24 h on all surfaces except human skin. It survived best on leather, plastic, and string. It survived less well after 6 h on wood, cotton, and rubber and after 60 min on metal. On human skin, PSTVd remained infective for only 30 min. In general, rubbing surfaces contaminated with dried infective sap directly onto leaves caused less infection than when the sap was rehydrated with distilled water but overall results were similar. The effectiveness of five disinfectant agents at inactivating PSTVd in sap extracts was investigated by adding them to sap from PSTVd-infected leaves before rubbing the treated sap onto leaves of healthy tomato plants. Of the disinfectants tested, 20% nonfat dried skim milk and a 1:4 dilution of household bleach (active ingredient sodium hypochlorite) were the most effective at inactivating PSTVd infectivity in infective sap. When reverse-transcription polymerase chain reaction was used to test the activity of the five disinfectants against PSTVd in infective sap, it detected PSTVd in all instances except in sap treated with 20% nonfat dried skim milk. This study highlights the stability of PSTVd in infective sap and the critical importance of utilizing hygiene practices such as decontamination of clothing, tools, and machinery, along with other control measures, to ensure effective management of PSTVd and, wherever possible, its elimination in solanaceous crops.
