Изучено влияние на репродуктивную функцию коров белково-витаминно-минеральных концентратов (БВМК) с кормовой добавкой «AMG-COMPLEX», состоящей из эфирных масел и растительных экстрактов. Для проведения опыта были сформированы контрольная и опытная группы по 70 голов с учетом количества дней до отела из коров второй и третьей стельности. Животным контрольной группы скармливали основной рацион. Для коров опытной группы были составлены рационы с БВМК, которыми заменяли пропорциональное количество концентрированных кормов и часть витаминно-минерального премикса. Они получали БВМК для сухостойных коров в количестве 300 г на 1 голову в сутки с 60-го по 20-й день до отела и по 200 г на 1 голову в сутки с 20-го дня до отела. После отела 60 дней им скармливали БВМК для раздоя в количестве 1200 г на 1 голову в сутки. Использование БВМК в рационах коров опытной группы способствовало улучшению у них репродуктивной функции и снижению частоты гинекологических заболеваний после отела в 4,5 раза. Индекс осеменения в опытной группе составил 1,73 (P≤0,05), что на 0,76 ниже, чем у животных контрольной группы. Средняя продолжительность сервис-периода в опытной группе составила 87,71 дня (P≤0,01) и была короче, чем в контроле, на 14,72 дня. The effect on the reproductive function of cows of the protein-vitamin-mineral concentrate with the feed additive ʺAMG-COMPLEXʺ, consisting of essential oils and plant extracts, was studied. To experiment, taking into account the number of days before calving, control and experimental group of 70 heads each were formed from cows of the second and third pregnancy. In the scientific and economic experiment, the cows of the control group consumed the feed of the main rations. For the cows of the experimental group rations were made with PVMC, which replaced the proportional amount of concentrated feed and a part of the vitamin-mineral premix. They received PVMC deadwood in the amount of 300 g per 1 head per day from 60th to 20th day before calving and 200 g per 1 head per day 20 days before calving. 60 days after calving they received PVMC lactation in the amount of 1200 g per head per day. Feeding PVMC to cows of the experimental group contributed to the improvement of reproductive function and a decrease in the frequency of gynaecological diseases after calving by 4.5 times. The insemination index in the experimental group was 1.73 (P≤0.05), which is 0.76 lower than in the animals in the control group. The average duration of the service period in the experimental group was 87.71 days (P≤0.01) and was shorter than in the control by 14.72 days.

ABSTRACT The interaction Fusarium oxysporum f. sp. cubense (Foc) x nematode and the genetic variability of Foc are the main problems with potential to affect the use of resistant varieties in the management of the Panama disease. The objective of this work was to evaluate the interaction between Foc and Meloidogyne javanica on the banana of the Prata Anã, Grande Naine and BRS Princesa cultivars. The experiment was conducted in a randomized block design, with six treatments and ten replications, which differed in the inoculation time of each pathogen. Simultaneous inoculation with Foc and M. javanica, inoculation with Foc one week before inoculation with M. javanica, and inoculation with M. javanica one week before inoculation with Foc. In addition to the controls, Foc isolated, M. javanica isolated, and cultivars without the pathogens. The seedlings were transplanted in 3-liter pots with sterile soil infested with 40 grams of Foc inoculum at the concentration of 1x106CFU/gram and 1000 eggs and J2 of M. javanica. At the end of 56 days, the treatments with 'Grande Naine' presented the highest reproduction factors of M. javanica. In the 'Prata Anã' no interaction was observed between Foc x M. javanica. The treatments with simultaneous inoculation of the two pathogens, and with Foc a week before, in the 'BRS Princesa', presented the highest external disease indices (DI), which promoted the highest AUDPC. The highest internal DI were observed in the treatments Foc+Mj+Grande Naine, Foc+Mj+BRS Princesa, Mj+Grande Naine+Foc and Foc+BRS Princesa+Mj. The simultaneous presence of M. javanica and Foc increases the severity of the Panama disease in Grande Naine and BRS Princesa cultivars.

Fungitoxic Effect

The antifungal activity of aqueous extracts of nine plants viz, Azadirachta indica, Parthenium hysterophorus, Momordica charantia, Allium sativum, Eucalyptus globules, Calotropis procera, Aloe vera, Beta vulgaris and Datura stramonium were assessed in vitro against Fusarium oxysporum f. sp. melongenae, Rhizoctonia solani and Macrophomina phaseolina, the soil borne phytopathogens. The assessment of fungitoxic effect was carried out by using three different concentrations i.e., 5, 10 and 20% against the test fungi, in terms of percentage of mycelial growth inhibition. The extract of A. sativum completely inhibited the mycelial growth of M. phaseolina at all the concentrations. The extracts of D. stramonium and E. globulus inhibited the mycelial growth of R. solani of 72%, and 70.7% respectively at 20% concentration, that of A. sativum, E. globulus and D. stramonium exhibited inhibition percentage of 63.3%, 61.8% and 61.1% respectively at 20% concentration on Fusarium oxysporum f. sp. melongenae. The application of plant extracts for disease management could be less expensive, easily available, non-polluting and eco-friendly.

Panama disease caused by Fusarium oxysporum f. sp. cubense has devastated banana production worldwide. This work aimed to determine effective disinfectants against two races of F. oxysporum f. sp. cubense, race 1 and tropical race 4 (TR4), for implementation with on-farm biosecurity procedures against this disease following the outbreak of TR4 in North Queensland in 2015. A total of 32 commercial disinfectants were screened and their activity was assessed after ≤30 s, 5 min, 30 min, and 24 h of contact with an F. oxysporum f. sp. cubense suspension containing 105 chlamydospores/ml without and with soil added (0.05 g/ml). Of the disinfectants tested, the quaternary ammonium compounds containing ≥10% active ingredient were found to be the most effective against both F. oxysporum f. sp. cubense races. These products, when used at a 1:100 dilution, completely inhibited the survival of all F. oxysporum f. sp. cubense propagules across all the contact times regardless of the absence or presence of soil. The bioflavonoid product EvoTech 213 and bleach (10% sodium hypochlorite) used at a 1:10 dilution also eliminated all F. oxysporum f. sp. cubense propagules across all the contact times. None of the detergent-based or miscellaneous products tested were completely effective against both F. oxysporum f. sp. cubense races even used at a 1:10 dilution. Soil decreases the efficacy of disinfectants and therefore must be removed from contaminated items before treatments are applied.

Abstract A description is provided for Fusarium oxysporum f.sp. cubense. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On cultivated banana and abaca (Musa spp.) and wild spp. of Heliconia (Musaceae), esp. H. caribaea (42: 80); three species of grass (Paspalum fasciculatum, Panicum purpurascens andlxophorus unisetus), and Commelina diffusa (Commelinaceae) may serve as alternative hosts (Waite & Dunlap, 1953). DISEASES: Panama disease (vascular wilt) of banana (banana wilt) and vascular wilt in abaca (Musa textilis). GEOGRAPHICAL DISTRIBUTION: Widespread: Africa, Asia, Australasia and Oceania, C. America and W. Indies, N. & S. America (CMI Map 31). TRANSMISSION: Primarily soil-borne; possibly air-borne also. Pathogen may spread in infected leaf trash or soil and debris in surface flood-water. Infected planting material is another source of infection and spread.

The aim of the present study was to scrutinize the response of banana (Grand Naine variety) plants when interacting with dead or live pathogen, Fusarium oxysporum f.sp. cubense, a causative agent of Panama disease. Response of plants was evaluated in terms of induction of defense-related marker enzyme activity, namely, peroxidase (POX), polyphenol oxidase (PPO), -1,3 glucanase, chitinase, and phenolics. Plant's interaction with live pathogen resulted in early induction of defense to restrain penetration as well as antimicrobial productions. However, pathogen overcame the defense of plant and caused disease. Interaction with dead pathogen resulted in escalating defense response in plants. Later on plants inoculated with dead pathogen showed resistance to even forced inoculation of live pathogen. Results obtained in the present study suggest that dead pathogen was able to mount defense response in plants and provide resistance to Panama disease upon subsequent exposure. Therefore, preparation from dead pathogen could be a potential candidate as a biocontrol agent or plant vaccine to combat Panama disease.
