Phytosanitary Products Action to Control Leaf Miner, Rust and their Influence on Coffee Vigor and Productivity

Abstract The Coffee Leaf Miner – CLM and coffee rust are the main pests and coffee diseases, respectively. One of the rust and CLM handling ways is the preventive use of active ingredients of joint action (fungicide + insecticide) via soil. These products are generally evaluated for their efficiency in the chemical control of pests and diseases; however some of these products may promote a tonic effect by improving plant vigor. Thus, the objective in this work was to verify the influence of the phytosanitary products application on the rust and leaf miner control, on the coffee trees development and production. The assay was installed in Random Block Design – RBD, with twelve treatments T1 – Premier Plus, T2 – Premier Plus and Actara, T3 – Verdadero, T4 – Verdadero and Actara, T5 – Actara, T6 – Actara (Nov/Feb), T7 – Altacor, T8 – Altacor and Actara, T9 – Impact, T10 – Opera, T11- Control and T12 – Practical and three replicates in a Catuaí IAC-144 crop. Number of nodes per branch, productivity, incidence of rust and CLM were evaluated. There was no difference in the coffee trees growth submitted to the application of different phytosanitary products for the control of rust and leaf miner. The application of Thiamethoxan + Cyproconazole in november with a complementary application of Thiamethoxan in february were more efficient for the coffee leaf miner control and provided greater vigor and productivity to the coffee tree.

Influence of Sulfur and Boron on the growth and yield of Broccoli

Abstract Field experiment was conducted to study the impact of sulfur (S) and boron (B) on yield and yield component of broccoli. Sulfur was applied @ 0 (control), 20 and 40 kg ha-1 as elemental sulfur while B was applied at the rate 0, 1 and 1.5 kg ha-1 as borax along with a basal dose of N,P and K @ 120, 90 and 60 kg ha-1. All the fertilizers were applied at the time of sowing. The experimental design used was randomized complete block design (RCBD) with three replications. The data on plant height, number of leaves, flower diameter, head yield and biological mass were recorded along with S and B concentration in soil after crop harvesting. The result revealed that yield and yield parameter increased with increasing levels of S and B with higher head yield, flower diameter and plant height were observed when 40 kg ha-1 S and 1.5 kg ha-1 B were applied. It was further noted that head yield and head diameter were non-significant when averaged across the B treatment between 20 and 40 kg ha-1 applied S but significant from control. Similarly, when the yield parameters were average across the S treatment, there was a significant and linear increase with higher B level. Soil analysis showed that both B an S concentration in soil increased by increasing level of applied S and B. So the optimum level of S and B for broccoli was 40 and 1.5 kg ha-1respectively for higher yield of broccoli.

About non – coding RNAs

Abstract The central dogma of molecular biology states that DNA makes RNA and RNA makes protein. Recently, a large number of RNAs have been identified in animal and plants that have little or no protein – coding potential. Such RNA molecules have been discovered by the extensive applications of high – throughput sequencing technology. Non – coding RNAs (ncRNAs), which comprise a significant output of the genomes of prokaryotes and especially eukaryotes, are increasingly implicated in the molecular mechanisms that are being used for responding to biotic and abiotic stresses that occurred in living things life. The ncRNAs are a heterogeneous group of RNA molecules, which can be classified in different ways according to their location, length, and biological functions. In this review a brief description about non – coding RNAs will be brought especially in plants.

Zeolite membranes to immobilize Catalase

Abstract Processes based on immobilized enzymes have been studied extensively in the last few decades and today are also applied to the safeguard of environmental parameters. In this work, zeolite composite flat membranes with different chemical composition, transition metal, and microporous structures were prepared using in situ and secondary growth crystallization synthesis methods in/on stainless steel porous disks. All zeolite materials were been used in catalase adsorption to analyze the zeolite behavior andthe effect of chemical composition and structure on interaction with the enzyme. This study shows that the electrostatic type of interaction seems to be of the utmost importance in influencing immobilization, while the zeolite Brönsted acidity of the support is the subordinate parameter, which differentiates the adsorption performances of different zeolite structures (that distinct for chemical composition of the framework). Moreover, it permits to conclude that transition metal-containing membranes adsorb a higher percentage of the enzyme with respect to no-exchanged membranes and that, for all materials synthesized, the amount of catalase adsorbed onto the zeolite crystals and membranes increases with the temperature.

A mitochondrial DNA SNP is maternally inherited in hops (Humulus lupulus, L.) and segregates varieties of the renowned Brewer’s Gold female lineage from the others

Abstract The integration of molecular biology concepts and techniques in cultivated plant breeding programs allows defining more accurately the parents involved in crosses. The analysis of the DNA polymorphism in existing hop cultivars or wild types selected to generate new potent varieties is commonly used. Ribosomal DNA RFLP was the first to be studied in the middle of the 1990’s and differentiated at least European from North American cultivated hops. The EcoRI rDNA RFLP has been established here for a selection of 31 H. lupulus plants, 17 of which are cultivars and the remaining 14 include wild types and other genotypes used for breeding. The sequence of the Magnum variety rDNA EcoRI fragment (4,957 bp) covering the intergenic spacer and corresponding to its North American heritage has been determined. As mitochondria are known to play a role in the biosynthesis of the valuable plant secondary metabolites, specially those based on isopentenyl pyrophosphate, the search for mtDNA polymorphism allowing a possible distinction among hops was engaged. After having established the 14,472 bp sequence of mtDNA encompassing the ATP synthase alpha subunit (509 aa), a 560 bp region 5’ upstream of this gene allowed to identify a single nucleotide polymorphism. This SNP appeared to be maternally inherited in the lineage of Brewer’s Gold, often used in crosses for its bittering properties. This work may stimulate researchers to explore further on the role of mitochondria in the biosynthesis of metabolites, mainly but not only isoprenoids, that make Humulus lupulus so interesting.

In vitro Evaluation of the Effectiveness of Some New Fungicides in the Control of Rhizoctonia solani in Tobacco Seedlings

Abstract The damping off disease of tobacco seedlings caused by the pathogen Rhizoctonia solani causes a huge damage. The limited numbers of products are used in protection from the disease, but lately new fungicides appeared on the market.

The aim of these investigations was to determine the effectiveness of new fungicides in control of this pathogen, compared with commonly used. The tests were carried out in conditions in vitro, with 8 fungicides. Two fungicides were evaluated in 2 or 3 concentrations.

All tested fungicides showed extremely high effectiveness in the control of this pathogenic fungus –the percentage of inhibition of radial growth ranges from 80, 45 to 100%.

The preparate Orvego (300 g / l ametoctradin + 225 g / l dimetomorph) is exception –it showed 48.05%.

The best effectiveness showed contact fungicides Manfil 80WP (800 g/kg mancozeb) and Enervin WG (120 g/kg ametotradin +440 g/kg metiram) as well as systemic Signum 33 WG (267 g/kg boscalid +67g/kg pyraclostrobin) and Quadris 25 SC (250 g/l azoxystrobin)with100%inhibition of pathogenʼs development.

Fungicides with such high effectiveness in control of R.solani will ensure their use in protection of tobacco seedling from the damping off disease.

Sustainability in Potato Production, According to Crop -Livestock Integration System Approach

Abstract: In the southern region of the State of Minas Gerais, Brazil, there is predominance of small farms that cultivate potato and exploit and dairy farming in family business form. These firms are important for the economic activity in the region, although most pasture areas are degraded. In Potato cultivation the intensive use of the area predominates with more than one crop per year, with absence of: technology, conservation and environmental techniques and crop rotation. This predatory system has led to the degradation of soils and natural resources. The purpose of this paper was to propose and disseminate techniques for crop managing and, mainly, the adoption of the crop-livestock integration system with potato as the main crop, providing for family business rationality and sustainable exploitation of its property. These practices can improve the income producers, and ensure the permanence in their properties. The research was carried out in three municipalities in the southern region of the state of Minas Gerais, prioritizing the sequence of rotational occupation and planting time of the potato: a) potato (planting in October), maize + Brachiaria grass (direct grazing and silage), millet (grazing); b) potato (February planting), oats (cutting and grazing), corn (grain); c) potato (October planting), maize; occupational sequence of crop rotation performed respectively in three municipalities. After the crops in succession, the potato planting is again restarted. The results obtained allow us to conclude that the crop-livestock integration system adds positive effects of potato production to those of livestock production, with a great synergistic effect benefiting all these operations.

Study on the Physico-Chemical Characteristics of Value Added Banana Products

Abstract The present study evaluated physico-chemical and sensorial qualities of value added banana products. Unripe fruits of Cavendish variety were processed for making banana flour. Value added products like dough, chapatti and banana kheer were prepared from banana flour. Rice and basin flour were also used in chappati. Unripe banana fruit, banana flour and their products were analysed for pH, titratable acidity, moisture (%), TSS (Brix) and vitamin C. The results showed that the maximum pH (7.68) and TSS (26.30 brix) recorded from the kheer, However, Ash (0.86%) and vitamin C (18.3mg/100gm) were observed highest in chapatti prepared from banana and rice flours as compared to chappati prepared from banana flour only (12.54). Unripe banana fruits had maximum percentage of moisture (72.08%) in comparison to banana products. The minimum pH (6.79) and titratable acidity (0.02) were observed from the unripe banana fruits. While, banana flour had minimum moisture (7.49%). Minimum TSS (5.30) were recorded in chappati prepared from mixture of banana-rice flour and banana-basin flour. The results shows that processing of banana for value added products alter the physico-chemical qualities of banana.

Physico-Chemical, Functional and Sensory Properties of Composite Bread prepared from Wheat and defatted Cashew (Anacardium occidentale L.) Kernel Flour

Abstract This study is part of the valuation of the cashew nut (Anacardium occidentale L.). For this purpose, defatted cashew kernel flour (powder) has been incorporated into wheat flour for the production of breads. Composite flours containing 0%, 10%, 20%, 30% and 40% of delipidated cashew kernel were analyzed for their physico-chemical and functional properties as well as the resulting loaves, for their sensory quality. The results showed that the substitution of wheat flour with cashew nuts flour increases the protein, fat, ash, fiber, energy and mineral content of wheat / cashew nut composites flours. However, this incorporation has resulted in a decrease in carbohydrate content. The study of the functional properties of composite flours showed that the substitution resulted in a significant increase (p <0.05) of the water absorption capacity (CAE) and oil (CAH) while the density decreased. Sensory tests indicated that there is a significant difference (p <0.05) between control bread and all composite breads. However, it is suggested that cashew kernel flour could be suitably incorporated into wheat flour up to a rate of 20%.
