“…O gênero Colletotrichum é capaz de causar infecção também em plantas de interesso na medicina como o cártamo (Carthamus tinctorius) que é uma espécie cultivada de importância medicinal e industrial e atualmente é considerada uma planta de grande potencial na produção de biodiesel. Carneiro et al (2012) verificaram qual o agente causal de lesões foliares de plantas sintomáticas e realizaram teste de patogenicidade dos isolados. A observação e análise de estruturas reprodutivas do patógeno em meio de cultura e no tecido do hospedeiro, assim como a PCR táxon-específica permitiram a identificação dos isolados do fungo como pertencentes à espécie Colletotrichum gloeosporioides.…”

Como alternativa da inserção de novas culturas na região do Semiárido brasileiro temos o figo 'Roxo de Valinhos' (Ficus carica L.) uma planta família Moraceae que pode muito bem ser inserida no contexto da agricultura familiar, mas que vem sofrendo infecção por um fungo do gênero Colletotrichum provocando importantes percas econômicas no agronegócio e também no campo da pesquisa e extensão. Este trabalho teve como objetivo caracterizar a morfologia de isolados de Colletotrichum spp. causador de antracnose pós-colheita em frutos de Ficus carica L. cultivado experimentalmente no perímetro irrigado da São Gonçalo no município de Sousa-PB. Primeiramente identificou os frutos com sintomas de antracnose seguido de sua desinfecção com álcool a 70%. Logo fez-se montagem em lâmina de microscopia para um prévia avaliação do patógeno. O fungo foi isolado em Batata-Dextrose-Ágar a 25ºC durante 10 dias. Seguidamente foi feito o microcultivo no mesmo meio de cultura para a análise morfo-tintorial do micélio usando como corante azul de algodão e lactofenol de amann.

“…The fungus Colletotrichum gloeosporioides causes the disease known as anthracnose, which occurs in tropical and subtropical regions of the world. This fungus affects economically important crops such as cereals, legumes, vegetables, fruits, and ornamental species (Carneiro et al, 2012). C. gloeosporioides attack plants by generating lesions and dark, rounded spots, in addition to large and deep necrosis.…”

Brazil is one of the world leaders in the agribusiness sector tending to directly influence a growing dependence on imported inputs, specifically synthetic agrochemicals. At the state level, in 2013, Tocantins stood out in first place in the ranking of agrochemical consumers, however, these products can cause several problems, such as poisoning to humans, environmental contamination, and increased resistance to phytopathogens. Biological control is an alternative to the use of agrochemicals towards eliminating pests naturally by using living organisms called Biological Control Agents (BCA). Currently, fungi of the Trichoderma genus are some of the most used organisms in biological pest control for their relevant characteristics that favor them in terms of survival in the environment, such as high capacity to adapt to ecological conditions, potential to colonize the rhizosphere of plants, mycoparasitism, production of volatile and non-volatile metabolites. In addition, it works on plant growth and productivity. In general, the use of Trichoderma favors the control of soil pathogens, such as Rhizoctonia, Pythium, Sclerotinia, and nematodes. Thus, this review aims to demonstrate the importance of using Trichoderma in biological control, as well as to present an overview and perspectives of research developed by respondents in the Brazilian Midwest region and Tocantins state.

“…Petals, leaves, and seeds have medicinal values, but the spread of this crop is due to its high oil content, which serves for the biodiesel industry (Dwivedi, 2005;Carneiro, 2012). It is considered as an energy crop or as a source of renewable energy (Kafra, 1998;Feizi et al, 2010).…”

Allelopathy is a natural botanical effect in which certain crops release inhibitory substances which affect growth and development of other crops to the environment. The ability of plants to exhibit allelopathy vary among species. In Brazil, the allelopathic studies are restricted to common plants, such as corn, soy, wheat, and safflower. Given these factors, there are still many cultures as Ilex paraguariensis that are forgotten, even though, they play an important role in the regional cultivation. The aim of this study was to evaluate the effect of cold water extract of I. paraguensis leaves on germination rates, seeds early growth and speed of germination of Carthamus tinctorius L. sprayed with aqueous extract of mate. The extract production process consists in grinding mate leaves along with cold water and then filtering it to remove the particles. Concentrations of 0 (control), 25, 50, 75 and 100% of the extract were used to induce the treatment, considering 200 g of extracted adult fresh leaves per liter of cold water. The seeds were planted in individual tubes containing specific soil for cultivation and they were all sprayed manually every 3 days using the volume of 500 ml in appropriate concentrations. The experimental design was completely randomized as it follows: 5 treatments, 4 repetitions, and 1 safflower genotype. To carry out the analysis, the emergency data were collected until the thirtieth day. Considering the statistical analysis, there was no change resulting in allelopathic effect in the following rates: germination rate, first germination counting, average time of germination and percentage of germination, stem diameter, root length, and leaf dry mass, but it was observed that in the concentration T3 (50%), there was a significant increase in safflower growth in the following characteristics: leaf fresh mass, root fresh mass, leaf length, leaf area, and root dry mass.
