The greatest removal of turbidity from the residual water was obtained with 20 g/l of crude extract of moringa cake, with stirring times for the extraction of the crude extract of 35 and 60 minutes. Likewise, the dose of 125 mg/l presented the greatest reduction in turbidity by 82%. The results obtained in the research demonstrate that “moringa” cake is useful for treating wastewater produced in the production of passion fruit nectar, minimizing the turbidity of wastewater, resulting in a reduction in the environmental impact of effluents.","PeriodicalId":34452,"journal":{"name":"Manglar","volume":"24 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138966327","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 aim of the research was to evaluate the use of a hydrogel (plantagel with a composition of 96% non-toxic potassium polyacrylate) in the water stress of the PMV-581 purple corn crop and evaluate its development and performance. The treatments were at three doses of 50, 70, 90 kg ha-1 of hydrogel (plantagel) and a control without hydrogel application, the results indicate the T0 control treatment. Treatment T1 (with 12 irrigations and 50 kg ha-1 of hydrogel) and T2 (with 10 irrigations and 70 kg ha-1 of hydrogel) require the greatest number of irrigations (with 15 irrigations and without hydrogel application) and T3 (with 8 irrigations and 90 kg ha-1 of hydrogel) T3 obtained the highest yield of 6.50 t ha-1, with a water table of 1500.84 m3, lower than the rest of the treatments, concluding that the Hydrogel influences soil moisture retention and its effect is expressed in the yield of purple corn.

Its epidemiology is associated with several factors. Its control depends not only on environmental or genetic aspects but also on good beekeeping sanitary management. To identify some epidemiological aspects associated with varroosis in colonies from the Central Region of Chile and to establish possible relationships between them, 58 apiaries located in the Region of Valparaíso, Metropolitana, and O’Higgins were studied. The apiaries were monitored five times in different seasons. Factors related to management practices by beekeepers were incorporated through a qualitative survey. Infestation rates by Varroa sp. and the honeybee colony strength were measured in each case. Results indicated that infestation rates by Varroa sp. are variable in relation to management practices, especially in additional feeding (energy and protein supplements), and also, with the varroicidal treatment options. Despite beekeepers’ efforts to treat their colonies, the global prevalence of varroosis was close to 53%. This indicates that to effectively control this parasitosis, additional and standardized methodologies must be included, taking a holistic point of view, including selection, genetic improvement, biotechniques to control the mites, and in specific cases, coordinated territorial treatments.","PeriodicalId":34452,"journal":{"name":"Manglar","volume":"32 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138966130","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}

Firstly, fungi were isolated and identified, molecularly based on the internal transcribed spacer (ITS) gene. From blueberry, lemon, grape and golden berry. Chitosan coatings were prepared, with different concentrations of chitosan and ZnO nanoparticles. These coatings were evaluated in vitro on some of the isolated fungi using the inhibition zone technique. The prepared coatings showed antifungal effect against Alternaria Alternata (blueberry), Aspergillus tubingensis (lemon), Aspergillus niger (lemon), Thielaviopsis ethacetica (lemon) and Aspergillus niger (golden berry). It was determined that the concentration of chitosan NPs had no effect on the antifungal capacity of the coatings, while the ZnO NPs did have a directly proportional effect.
