Opis:: In this study, mycelial compatibility grouping (MCG) of Sclerotinia sclerotiorum (Lib.) de Bary was determined in 15 infected potato fields in Bahar and Lelehjin, Hamadan, Iran. Among 193 isolates, 37 MCGs were identified and 67% were represented by single isolates observed at single locations. Within Bahar fields, 29 MCGs were identified and 15 MCGs were recognized in Lalehjin samples. MCGs 2, 6, 18 and 25 were collected at high frequency from multiple locations. The efficacy of Potato Dextrose Agar (PDA) amended with activated charcoal for identifying MCGs in this fungus was tested in doubtful reactions and proved to be an effective medium. The activated charcoal produced a black reaction area in incompatible interactions as well as a red reaction line in PDA amended with McCormick's red food coloring.

Opis:: The efficacy of three types of mineral spray oil (MSO), and Abamectin plus MSO to control the citrus leafminer Phyllocnistis citrella Stainton were compared with the conventional broad spectrum pesticides, Confidor, and Dursban, in two citrus orchards in northern Iran. Differences were found among the various concentrations of MSO in the number of mines and live larva per leaf, sampled 5 days after the application of 3 sprays at an interval of 5 days. Mineral spray oil applied at a rate of ≥ 0.65% in water, showed no significant differences when compared with Confidor, and Dursban. Abamectin plus MSO at a rate of 0.02% plus 0.50% in water respectively, provided the highest level of control and reduced the population of larva up to 85%. Generally, a concentration of ≥ 0.65% MSO in water caused a significant damage reduction. However, by reducing the MSO concentration, the rate of control was decreased. In another field experiment conducted in mature citrus orchards, the effect of two pest management types (applying just MSO vs. usage of synthetic pesticides) on the activity of P. citrella, was evaluated. The comparison results indicated that there is more P. citrella damage in orchards under pressure of synthetic pesticides than in orchards in which the synthetic pesticides were eliminated for years.

Opis:: Arbuscular-mycorrhizal internal structures (i.e. total root colonization, arbuscules, vesicles) and external structures (i.e. spore density), and Glomeromycota spore morphotypes, were evaluated in wheat severely infected with Mycosphaerella graminicola - the causal agent of Septoria leaf blotch. Plots in which the infection was controlled with a commercial fungicide at recommended field doses, were also examined. The commercial fungicide used was an admixture of trifloxistrobin and tebuconazole. No negative effects of the fungicide application on arbuscular-mycorrhizal fungi (AMF) were found. The M. graminicola fungicidal treatment actually favoured the formation of arbuscules and AMF spores, as there was a selective increase in the density of spores belonging to the glomoid morphotype. Arbuscular-mycorrhizal fungi have an absolute dependence on the carbon provided by the plant. A severe foliar disease leading to a diminished carbon supply to the roots would generate decreases in carbon availability. Such decreases would strongly affect mycorrhizal associations and development. Furthermore, the change in the green-leaf area produced by a severe foliar disease and/or a reversal of that condition through fungicide treatment could result in shifts in the composition of the AMF community so as to favour glomoid morphotypes. Glomoid species have been previously considered as r-strategists.

Opis:: The role of the tea commodity in the economy of Indonesia is quite strategic. Various types of microorganisms in nature have been known to increase the benefit of the root function, suppress disease, and accelerate plant growth. This study aimed to determine the potential of indigenous bacteria (Azoto II-1, Acinetobacter sp., bacteria Endo-5, bacteria Endo-65 and Endo-76) on the growth of tea plants and their potential in increasing resistance to blister blight disease. The test of microbes’ potential effect on growth and blister blight was conducted in Gambung, West Java in an experimental field using a randomized block design (RBD) with six treatments and each treatment was replicated four times. The composition of the treatments was: A) Endo-5; B) Endo-65; C) Endo-76; D) Azoto II-1; E) Acinetobacter sp.; and F) control (without microbes). Bacterial suspension was applied directly to the soil at a dose of 2 l · ha−1. The bacterial suspension was applied six times at 1 week intervals. The results of field observations indicated that the intensity of blister blight decreased in all treatments but did not significantly differ from the control. Meanwhile, the results of Acinetobacter sp. treatment in tea shoots was 17.26% higher than the control.

Opis:: The granary weevil, Sitophilus granarius (L.), is one of the most important internal feeders of stored grain. Nanotechnology has become one of the most promising new approaches for pest control in recent years. In our screening program, laboratory trials were conducted to determine the effectiveness of silica nanoparticles (SNPs) and zinc nanoparticles (ZNPs) against the larval stage and adults of S. granarius on stored wheat. Nanoparticles of silica and zinc were synthesized through a solvothermal method. They were then used to prepare insecticidal solutions of different concentrations and tested on S. granarius. Silica nanoparticles (SNPs) were found to be highly effective against S. granarius causing 100% mortality after 2 weeks. ZNPs were moderately effective against this pest.

Opis:: To formulate an efficient and eco-friendly strategy for the management of cotton seedling disease complex, pot experiments were conducted and the efficiency of eight Bacillus strains against seven fungi involved in the disease were determined. A greenhouse evaluation of the interaction between fungal isolates and Bacillus strains was carried out. The evaluation revealed a very highly significant Bacillus strains x fungal isolates interaction for all the following parameters: preemergence damping-off, postemergence damping-off, survival, plant height, and dry weight. This interaction implies that a single strain of the Bacillus sp. can be highly effective against a fungal isolate, but may have only minimal effects on other fungal isolates. The results of the present study demonstrated that Bacillus circulans and B. coagulans were the most effective strains in controlling cotton seedling disease. Therefore, strains of Bacillus spp. should be tested against as many fungal isolates as possible. The testing will improve the chance of identifying Bacillus strains effective against several fungal isolates.

Opis:: This weed management investigation was carried out at the Zonal Agricultural Research Station (ZARS), Bangalore, during the summers of 2017 and 2018 to standardize agrotechniques for weed management of rice grown under aerobic conditions. The experiment was laid out in a randomized complete block design with eleven treatments replicated thrice. It consisted of two pre-emergence herbicides and one early post-emergence herbicide, the stale seedbed technique, mulching, hand weeding and intercultivation which was compared to the weedy check. The results showed that pyrazosulfuron ethyl 10% wettable powder (WP) at 35 active ingredient (a.i.) g ⋅ ha–1 as PE fb bispyribac sodium 10% SC at 30 ml ⋅ ha–1 a.i. as an early post-emergence herbicide performed better in terms of rice grain and straw yield (5,800 and 9,786 kg ⋅ ha–1, respectively), plant height (58.42 cm), rice total dry matter production (149.84 g ⋅ plant–1), productive tillers ⋅ hill–1 (40.32), panicle length (24.53 cm), 1000 grain weight (25.35 g), net returns (Rs. 62424), higher B : C ratio (2.59) and lower total weed density, weed dry weight at different stages of rice and weed index (3.80%) as well as higher weed control efficiency (90.52%). This practice could be recommended to farmers growing aerobic rice under these climatic conditions.

Opis:: Sugar beet is one of the most important industrial crops in Iran. For the last two decades it has been mainly affected by a destructive virus, beet necrotic yellow vein virus (BNYVV). The Polymyxa betae is the only natural transmitting agent of the disease among the plants. Developing accurate diagnostic methods may have a major impact on the rising of resistant germplasms. In the present study, specific monoclonal recombinant antibodies in the form of single chain variable fragments (scFv) were obtained from naïve phage display libraries. The fungus specific glutathione-S-transferase (GST) protein was chosen as an antigen for developing antibodies and diagnostic purposes. To generate specific scFv, screening of Tomlinson phage display libraries was performed by applying both recombinant and native fungal GST. Using the recombinant GST in the panning process resulted in the isolation of an antibody only bound to recombinant GST but it failed to detect native GST in the infected plants. Alternatively, the process of panning was carried out by applying native fungal GST trapped to immunotubes through specific polyclonal antibody intermediate. The recent approach resulted in the selection of a specific scFv binding to native GST which was able to detect the presence of the fungi within infected plants. To the best of our knowledge, this is the first report on the generation of recombinant antibodies against Polymyxa betae, fungal vector of sugar beet rhizomania disease.
