Results revealed that in all tested EPNs, LC50s were lower in larval stages than pupae. All nematode strains were not significantly affected by any of the tested concentrations of diazinox or basudin, i.e., IJs survival was held over 75% and 66% when checked by 1500 and 4500ppm, respectively. Insecticides exposure period affected to some extent the nematode survival regardless of their concentration. Z. pyrina highest mortality (100%) was obtained from the mixture of basudin (half recommended rate) and LC90 of EGB20 strain. Data extracted from field results recommends that, all tested nematode strains at 1000 IJs/ml proved to be more effective against Z. pyrina in olive tree than diazinox and basudin. The EGB20 strain showed superior effect over EGB13 and EBN16, especially with injection methods and addition of evaporation retardant agent. The joint action of mixing nematode strains together with insecticides as a co-toxicity factor did not achieve its goal or fulfilled our expectations. Yet, combinations of EGB13 and EGB20 strains, proved to be slightly higher in their effectiveness than using insecticides or entomopathogenic nematodes separately and multiple co-applications of insecticides and nematodes were associated with a longer protection period of olive trees. The current study might be an important step towards establishing an efficient control strategy capable of minimizing Z. pyrina population below economic thresholds in olive farms.","PeriodicalId":108838,"journal":{"name":"Amazonian Journal of Plant Research","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132560008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It started with explanation of different types of priming media: hydro-priming, osmo-priming, hormonal and chemical priming. It then examined optimum priming concentration and duration. It also looked into how seed priming improves yield and yield quality of different crops. It further examined how seed priming aids direct seeding, confers tolerance against drought, salinity and low temperature stresses in plants. In addition, it discussed how thermo-inhibition and oxidative stress are alleviated with seed priming. In the same vein, It explained some of the mechanisms of priming operation and answered the question on whether seed priming is a source of stress to seeds or not. Moreover, it justifiably elucidated biochemical and enzymatic changes, pattern of genetic expression, and proteomics of primed seeds and their resulting plants. Finally, it answered the question on whether seed priming has direct or indirect effects on plants.

Thus, this work aimed to evaluate the quality and useful life of pumpkins cv. Regional and Cabotiá minimally processed and stored at 10 oC for 12 days. Physicalchemical quality (mass loss, firmness and color index, soluble solids, titratable acidity, pH, SS/TA ratio) and sensory quality (aroma, whiteness incidence and overall quality) were investigated. During storage there was a significant increase (p<0.05) in weight loss and reduction in firmness index, color, soluble solids, titratable acidity and ratio (SS/TA), so that 'Regional' pumpkins were more resistant to the preservation of these characteristics over 12 days compared to Cabotiá. Regarding the sensory aspect both cultivars presented low whitish indexes, however, the characteristic aroma of fresh fruit as well as the overall quality measured as shelf life was significantly better (p<0.05) in the ‘Regional’ pumpkins.

This problem is most evident in the Brazilian Backwoods, mainly due to their edaphoclimatic conditions. In opposition to the agriculture challenges, on the other hand, activities of fish farming have been growing in Brazil. However, aquaculture is an activity that generates effluents with a high amount of organic matter (OM) and nutrients. In a dual perspective, to solve the problem of the low soil fertility and the toxic potential of the effluents generated in the fish farming, the implementation of integrated farming systems could be an interesting alternative, proposing to reuse the water from fishponds by enhancing OM and recycling nutrients via irrigation. Thus, the present work aims to carry out a chemical study of water from fishponds for use in irrigation of plants of economic interest. The soil collected and characterized in this study was a dystrophic Red-Yellow Argisol (dRYA). Samples of FFW and the dRYA was characterized and its physical/chemical attributes determined. According to the results, chemical characteristics allow the FFW the in the irrigation of plants with economic interest. Since dRYA is low in OM (2.12%), TOC (0.43%) and %V (47%), soil samples showed a non-natural fertility at a level of considerable profitability. Thus, according to our findings (about FFW and dRYA chemical characterization), it is possible to consider the use of water from fish farming in the soil/plant irrigation. At future, agronomic assays will be carried out in order to evaluate the real effects of the FFW irrigation in an organicagroecological farm, in a family nucleus system of production, in the Brazilian Backwoods. Key-words: Fish Farming Water, Brazilian Backwoods, Organic Matter, Organic Agriculture In recent decades, Brazil has passed from a major food importer to one of the most important exporters. In this sense, agriculture is extremely important for the overall performance of the country economy (Embrapa, 2018). Actually, one of the challenges in agriculture is the quality of the Brazilian soils, which are mostly low in natural fertility; since they are high weathered, acidic and poor in organic matter (OM) and nutrients, resulting in a low agricultural productivity (Manzatto et al., 2002). This problem is aggravated in the Northeast Region, which has a semiarid climate, characterized by a water deficit and an irregular rainfall pattern, resulting in a poor environment for agricultural production (Buainain and Garcia, 2013). On the other hand, fish farming activity has been growing in Brazil. In 2018, the country became the 4th largest fish producer in the world. Thus, Brazilian fish farming is a growing activity with a great potential due to the country water resources and favorable climate (Medeiros, 2019). In the Northeast Region, fish farming has been prominent, since the low rainfalls and the periods of prolonged drought make it difficult for ruminant creation and c","PeriodicalId":108838,"journal":{"name":"Amazonian Journal of Plant Research","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132701871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most commonly used control is the chemical, but the indiscriminate use of these products causes risks of environmental contamination and of rural workers. In the search for alternative methods of control, essential oils appear, which are natural plant products with antifungal, antibacterial and insecticidal properties, and present less risk to the environment. The objective of this work was to evaluate the in vitro antifungal activity of essential oils on the inhibition of mycelial growth of phytopathogenic fungi. The essential oils of bush avocado (Persea major), rosemary (Rosmarinus officinalis L.), garlic (Allium sativum L.), cinnamom-fire (Cryptocarya aschersoniana Mez.), sassafras cinnamom (Ocotea odorifera Vell.), lemon grass (Cymbopogon citratus), capitiu (Siparuna guianensis Aubl.), India clove (Syzygium aromaticum), guamirim (Myrcia splendens) guava brava (Myrcia tomentosa Aubl.), jatoba (Hymenaea courbaril L.), black peper (Piper nigrum L.), thyme (Thymus vulgaris L.) and annatto (Bixa orellana L.) against fungi Fusarium solani, Pestalotiopsis guepinii, Phytophthora spp., Rhizoctonia solani and Sclerotinia sclerotiorum. The mycelial growth of these fungi was evaluated by means of the Petri dish mycelial growth inhibition index containing the potato, dextrose, agar environment in the concentration of 1,000 μl/mL of the essential oils. The design was completely randomized with three replications. Among the essential oils used, the thyme and India clove promoted complete inhibition of all fungi tested.
