The Use of Some Micronutrients and Plant Extracts of Resistance to Powdery Mildew and Nutrition Dill Plants in The Gharbiyah Governorate

Abstract

This work was carried out during the two successive seasons of 2014/ 2015 and 2015 / 2016 at Private Farm in Sammnoud, Gharbiyah Governorate, Egypt, to investigate the utilization of some micronutrients (Zn and Mn) and plant extracts [garlic (Allium sativum L) and aloe (Aloe vera)] and their effects on plant growth, yield (fruit essential oil), chemical composition and control against powdery mildew (Erysiphe heraclei) in dill plants. The application of plant extracts with micronutrients showed increased plant growth, yield (fruit and essential oil) and control against powdery mildew compared to plant extracts or micronutrients individually. The highest values of plant growth and yield (fruit and essential oil) and the lowest percentages of powdery mildew incidence and severity resulted from sprayed plants by garlic extract plus Zn and Mn treatment. Thus our study provides the grater results for using garlic extract with micronutrients by farmers to have better yield from fruit and essential oil in dill plants, as well as reduce the incidence of powdery mildew, it is easy available, environmentally safe and cost effective.

Synergistic Effects of Biogas Fertilizer and Natural Extracts of Garlic, Azolla, and Yucca on the Vegetative Growth and Essential Oil Yield of Stevia Rebaudiana L. Plant Under South Sinai Conditions

“…These effects can also be due to the influence of garlic extract on growing levels of endogenous hormones in treated plants, (Khedr and Farid, 2000). These observations were consistent with (AbdelKader et al, 2014), (Ziedan and Eisa, 2016) on Anethum graveolens (Massoud et al, 2017) on Majorana hortensis L. plant. (El-Said and Ali, 2013) on Cumin.…”

Effect of Bio-Fertilizers, Plants Extracts and Active Dry Yeast on Marjoram Plants.

“…Garlic extract (Allium sativum) is rich in macro and micro elements, important plant hormones like Auxins, Gibberellins and Cytokinin which induce cell division and increasing cell enlargement and lead to balance of physiological and biological processes and increasing photosynthesis processes and improving growth qualities (Hanafy et al, 2012, Nour Eldeen, 2014and Ziedan and Eisa, 2016. The objective of the current study was to study the effect of some biofertilizers, active dry yeast and garlic extract as well as their combination on growth, essential oil and chemical composition of marjoram plant.…”

Response of Stevia (Stevia Rebaudiana L.) to Biogas Fertilizer and Natural Extracts Under South Sinai Conditions

“…These effects can also be caused by the impact on the growth of the endogenous hormones all in treated plants of garlic extract; (Abd-Allah et al, 2021). These observations corresponded to (Ziedan and Eisa, 2016) on dill plant who concluded that using garlic extract with micronutrients to have better yield from fruit, it is easily available, environmentally safe and cost-effective, (Massoud et al, 2017) on Majorana hortensis L. (Massoud et al, 2019) on Caraway and(AbdelKader et al, 2014), on Salvia officinalis L. Also the increases of photosynthetic pigment content, maybe due to a higher soil and nutrient retention and supply. This increase in photosynthetic pigment creation could also be a result of Azolla cytokinins' ability to prolong leaf aging by inhibiting chlorophyll breakdown and promoting protein and RNA synthesis (Castelfranco and Beale, 1983).…”
