“…Zhang et al (2016) stated that Hcm1containing harpin protein suppresses the growth of V. dahliae and Fusarium oxysporum in vitro, and that Hcm1 can activate innate immunity. Aysan et al (2019) have reported that salicylic acid (SA) and Fosetyl-Al at concentrations above 700 μg/ml in vitro suppressed mycelial growth of strawberry black root rot caused by R. solani, plant activators such as Acibenzolar-S-Methyl (A-S-M), Messenger, ISR-2000, Crop-Set did not inhibit mycelial growth of the pathogen. Our results are not similar to Şahbaz and Akgül (2016) found that the plant activators Fosetyl-al, SA, A-S-M + Metalaxyl-m and ISR-2000 did not inhibition against mycelial growth of F. oxysporum f. sp.…”

Wilt disease caused by Verticillium dahliae Kleb. is one of the stress factors affecting yield and fiber quality traits in cotton cultivation. Plant activators provide resistance by stimulating genes that activate the resistance mechanism in the plant. The aim of this study is to determine the effect of plant activators such as auxiGRO, Green Miracle, Maxicrop, ProAct Plus and Sojall Vitanal against verticillium wilt under both in vitro and in vivo conditions. Firstly, the effect of various concentrations of plant activators (0, 1, 5, 25, 100, 250, and 500 ppm) on mycelial growth two fungal isolates of V. dahliae (PHCVd3-non-defoliating pathotype and PHCVd47-defoliating pathotype) in potato dextrose agar media was investigated in vitro. The effect of plant activators on V. dahliae was determined in tolerant cotton plants (cv Carmen) and in susceptible cotton plants (cv Acala SJ2) in two different ways as seed coating and foliar application in vivo. In vitro experiments were carried out with three replicates, and in vivo experiments were with five replicates depending on a completely randomized plots design. 500 ppm dose of all plant activators inhibited mycelial growth of both isolates by approximately 90%. The lowest disease index (DI) against PHCVd3 was determined as 1.43 in the tolerant cv Carmen with seed coating of auxiGRO. The lowest DI against PHCVd47 was found in Sojall Vitanal and ProAct Plus as 2.09 and 2.12, respectively. The lowest DI against both isolates were found as 1.42 and 2.18 in cv Carmen by foliar application of ProAct Plus, respectively. Plant activators did not show any inhibitory effect on disease severity against both isolates in cv Acala SJ2. The combination of tolerant cultivar + plant activators can be suggested against verticillium wilt disease as alternative control.

Late blight caused by Phytophthora infestans is one of the most important fungal diseases that cause damage to both the green parts and tuber of the potato plant and limits potato cultivation. Systemic fungicides are mostly preferred by farmers in the control of potato late blight. The fact that systemic fungicides cause health problems in terms of human and environmental health has revealed the need for research on control methods that do not threaten environmental health. In recent years, successful results have been obtained in the control of many diseases with plant activators known as Induced Systemic Resistance (ISR) promoters. This study was carried out in the spring season of 2016-2017 to observe the effect of copper fungicide and plant activator (Lactobacillus acidophilus fermentation product) combination on the control of potato late blight disease and some quality criteria of potato tubers in the experimental plots of Ege University Ödemiş Vocational School in Ödemiş district of İzmir province. The experiment was planned as two separate experiments with Marabel and Melody potato cultivars. The experiment was established according to a split-plot experimental design with four replications. In this study, the effect of the treatments on potato quality and yield criteria such as tuber number, tuber width, tuber length, single tuber weight, yield per decare, and the effects of the pesticides on potato late blight disease and disease severity parameters were evaluated. When the data obtained as a result of the study were evaluated, it was determined that the combination application had a positive effect on the control of potato late blight disease in both potato cultivars compared to the control plots. When the quality criteria of potato tubers were evaluated, the highest number of tubers was obtained from the plots where copper fungicide and plant activator (Isr-2000) combination was applied. Significant increase was obtained in potato quality and yield criteria such as tuber width, tuber length, average tuber weight and yield per decare when the combination plots were compared with the control plots. In conclusion, the use of contact fungicides and plant activator combinations in the control of late blight in the spring period within the scope of sustainable agriculture is promising as an application alternative in the control of plant diseases in organic agriculture.

Bu çalışma ile bazı organik madde uygulamalarının (zeytin karasuyu, tavuk gübresi, kükürt, pamuk delintasyon atığı, vermikompost; bitki artığı olarak soğan, pırasa, karnabahar, brokoli, lahana, buğday, bakla, marul, hardal bitkileri) çilek bitki gelişimi ve Macrophomina phaseolina’nın çilekte neden olduğu taç ve kök çürüklüğü ve mikrosklerot popülasyonu üzerine etkisini incelemek amacıyla yürütülmüştür. Organik madde uygulamalarının doğrudan mikrosklerot popülasyonu, çilekte bitki gelişimi ve M. phaseolina’nın neden olduğu taç ve kök çürüklüğü hastalığı ve bitkiler söküldükten sonra bu saksı topraklarında mikrosklerot popülasyonu üzerine etkisi araştırılmıştır. Bu amaçla organik madde karıştırılmış steril topraklara çilekten izole edilmiş M. phaseolina izolatı (Omp1) mikrosklerot 50 ms/g olacak şekilde inokule edilmiş ve 30 gün inkube edilmiştir. Bu topraklardan yapılan mikrosklerot izolasyonlarında, topraktaki en düşük mikrosklerot sayısı sırasıyla zeytin karasuyu (0.8 ms/g toprak), brokoli (2.5 ms g-1 toprak), vermikompost (6.0 ms g-1 toprak) ve hardal (6.7 ms g-1 toprak) olarak saptanmış, pozitif kontrolde ise 1 g toprakta 84 mikrosklerot saptanmıştır. Organik madde uygulamalarında bitki gelişimine etkisi açısından en iyi sonucu sırasıyla %84.5 ağırlık artışı ile tavuk gübresi, %66 ile kükürt (100 kg da-1) ve %61.9 ile kükürt (50 kg da-1) uygulamalarında olmuştur. M. phaseolina’ nın neden olduğu taç ve kök çürüklüğü hastalığı açısından ise bitkilerin ağırlık değişimlerinin %-20.4 ile %42.7 arasında değiştiği saptanmıştır. Kükürt (50 kg da-1) uygulamasında %42.7 oranında ağırlık artışı saptanırken bunu, %37.9 ile kükürt (100 kg da-1) izlemiş pırasa uygulamasında ise %20.4 oranında bir ağılık kaybı olmuştur. Çalışmada bitkiler söküldükten sonra saksı toprağında saptanan mikrosklerot sayıları ise Karnabahar+Mp uygulamasında 1 g toprakta 12 mikrosklerot saptanırken Kükürt 100 kg da-1+Mp uygulamasında 1 g toprakta 28.8 ile en yüksek mikrosklerot sayısı saptanmıştır. Sonuç olarak, gelecekteki çalışmalar, toprağın fiziksel ve kimyasal özelliklerine bağlı olarak en uygun zamanlamanın yanı sıra organik madde miktarı ve türü ile çevresel koşulları ele almalıdır.
