A systematic review focused by plant on non-target impacts from agents deliberately introduced for the biological control of weeds found significant non-target impacts to be rare. The magnitude of direct impact of 43 biocontrol agents on 140 non-target plants was retrospectively categorized using a risk management framework for ecological impacts of invasive species (minimal, minor, moderate, m...
Sweet flag (Acorus calamus) is a perennial, semi-aquatic and aromatic plant of the family Acoraceae that, in addition to its multiple medicinal properties, is used in health, food and agricultural industries (as pest control). This research was conducted to comparasion study of genetic diversity of natural and regenerated plants from tissue culture of Arzefon, Pelesk and Alandan populations of ...
Rhizomania disease is one of the most important diseases of sugar beet in Iran and many other parts of the world, and plays an essential role in decreasing sugar yield in fields. The best approach to control this disease is to use resistant varieties. For the involvement of resitance genes in breeding programs, tagging these genes by molecular markers is necessary. In this approach, some breedi...
Background and purpose: Several studies have shown differences in HTN prevalence between urban and rural populations. The aim of this study was to compare the prevalence of HTN and the status of HTN awareness, treatment and control between Iranian urban and rural populations aged over 20 years. Materials and Methods: As a part of a nation-wide survey in 2004 on risk factors of non-communic...
two separate greenhouse experiments were conducted in the greenhouse of the iranian plant protection research institute, tehran, to compare the efficacy of some acetyl coa carboxylase (accase) and acetolactase synthase (als) inhibiting herbicides in control of wild oat biotypes. in each experiment, populations were independently treated by 10 herbicides each in 12 replications. to evaluate the ...
Abstract Background Insecticidal proteins from the Bacillus thuringiensis ( Bt ) marks genetically modified cotton crop that was commercialized in India March 2002 for control of lepidopteron bollworms. Despite organized initial control, pink bollworm (PBW), Pectinophora gossypiella (Saunders), adapted itself to cry toxins resulted field failures 2016 and 2017. The present study designed unders...
Thyme is one of the best known genera within Labiatae family, because of its more than 250 species and its antimicrobial and antispasmodic uses. At the present time, demand for thyme products are increasing and hence research demand is increasing. Environmental factors such as drought can affect plant growth and production. Phytohormones take a crucial role in this stress. Indicated T. serpyllu...
Abstract Background Bacterial wilt caused by Ralstonia solanacearum is considered one of the most important diseases that cause economic losses to many crops and spread in regions around world, especially subtropical tropics some warm temperate world. In this study aqueous plant extract Rosemarinus officinalis Pseudomonas fluorescens for their antagonistic activity against bacterial vitro, gree...
rhizomania is the most important disease of sugar beet in iran and some other parts of the world, and plays an essential role in decreasing sugar yield in fields. the best approach to control this disease is to use resistant varieties. tagging the resistance genes in breeding programs, by molecular markers is necessary. in this study, some breeding populations and commercial varieties of sugar ...
this research was conducted to examine the effect of a concurrent training on rest level of leptin of plasma and some hormonal factors in non-athlete subjects. the research population included non-athlete men who didn’t participate in any organized sport activities. 30 men were chosen voluntarily among the above-mentioned population and were divided into 2 groups: experimental (15 subjects) an...
