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. Garlic essential oil and lemon grass completely inhibited the mycelial growth of three of the five fungi tested.

The range of the green operations is large; yet, the topping of shoots and the special treatment of the side-shoots remain two of the most important interventions whose impact on the product indicators is undeniable. These operations aim to balance the vegetative growth and the bunch productivity, by redirecting part of the organic substance of the shoots to the bunch growth. It has been observed that these interventions influenced the pollination potential, which resulted in an increase of the grape grains in the bunch. There is a relation between the time and the frequency of the light topping of the shoots whose impact on the vine activity is great. Various intensive toppings of the shoots bring different results in different ecological contexts and cultivars. Heavy late toppings, especially in cold regions Korçë, have negative impact, since the action extends the vegetation period and prevents proper maturity of the shoots. These interventions become more delicate when it comes to cultivars with middle or long-term ripening period, like the Black Serin cultivar (vitis vinifera). The current study aims to instruct vinedressers about the proper time and frequency of the topping of this cultivar, in order to create a possible vegetation and production equilibrium, as well as qualitative ripeness of the grape.","PeriodicalId":108838,"journal":{"name":"Amazonian Journal of Plant Research","volume":"11 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":"125832995","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}
