Abstract

Management of soil borne disease of tomato with the aim of reducing the use of chemical pesticides and produce healthy products needs to provide appropriate policy. Grafting is one of the most effective control measures of soil borne pathogens result in healthy crop production and is an excellent substitute for chemical control. According to some investigations, grafting the commercial varieties on resistant rootstocks results in higher yield as well as the better quality. In addition to obtain higher product quality and optimize plant growth, disease management can be achieve by minimum application of pesticides.

Dadrezaei S. D. & Torabi M. 2016. Management of wheat rusts. Plant Pathology Science 5(2):81-89.

Wheat is the most important crop in the world and rust diseases cause the most damage to wheat all over the years. There are so many ways to control the disease that the use of resistant cultivars is the most effective and economic way for disease control. Rust has high pathogenicity diversity and evolutionary aptitude. On the other hand, migration and mutation leads to the emergence of non-native races of rusts in a region so virulent pathotypes with the new structures and violence on resistance genes in commercial resistant cultivars were incidence and cause disease in resistant varieties and spread in the wheat fields. Development of effective and sustainable control methods against plant diseases is very much dependent on our knowledge of the disease in our country. This paper introduces wheat important rusts diseases and explains Factors affecting the prevalence, distribution, and relation of air currents in the transmission of rusts and strategies for monitoring and management of rusts in the country.

Abootorabi E. 2017. Four marigold species as control agents of root knot nematodes. Plant Pathology Science 6(1):68-79.

The Root knot nematodes (Meloidogyne spp.) are major limiting factors in growing many agricultural crops. With the aim of producing a healthy crop, cultivation of some plants with allelopathic effects on nematodes is one of the most effective control measure against root knot nematodes. This method can be used as an excellent substitute of chemical treatment. Marigolds (Tagetes spp.) are herbaceous plants of family Astraceae with more than 50 species, can be used as ornamental cover crops. Nematicidal effects of marigolds on several nematodes had been proved. Marigolds produce alpha-terthienyl enzyme, which can control root-knot nematodes and other pests and pathogens such as fungi, bacteria and insects. It also has positive role in promoting growth of bedding plants. In this article, important marigold species including Tagetes tenuiifolia Cav., T. minuta L., T. patula L. and T. erecta L., have been introduced.

Abootorabi E, Ebrahimi L (2022) Introduction of three entomopathogenic nematodes of Iran and their impact on honeycomb moth. Plant Pathology Science 11(1):89-99.        
 Doi: 10.2982/PPS.11.1.89.
 
Introduction: The aim of this study was to collect and identify entomopathogenic nematodes native to Iran and to evaluate their pathogenicity on honeycomb moth larvae (Galleria mellonella). Materials and Methods: Thirteen isolates of entomopathogenic nematodes were collected from different provinces of Iran and identified based on morphological characters. The percentage mortality of G. mellonella larvae infected with these isolates at 25 ± 1 and 32 ± 1 °C was determined in a one-to-one assay, and the ability of the isolates to find a target and the mortality of the insect in the sand column test were determined. Results: Seven isolates of Heterorhabditis bacteriophora, two isolates of Steinernema feltiae, and five isolates of S. carpocapsae were identified. The ability of isolates of all three nematode species to penetrate the insect's body has been shown to be up to 93% within 48-72 hours post-infection at 25 ± 1°C. The optimum temperature for the biological activity of the identified isolates was 25±1°C. S. carpocapsae found a target faster than the other two species in the sand column test. Conclusion: Isolates of S. carpocapsae have higher potential in targeting and pathogenicity of honeycomb moth larvae than the other two nematode species.
