2. Selection of conilon coffee clones tolerant to pests and diseases in Minas Gerais
Abstract In the northern Minas region, the dry-warm climate predisposes coffee plants to the occurrence of leaf miners, mites, cercosporiosis, and leaf scald. Aiming for the development of a cultivar adapted to these conditions, Coffea canephora Pierre ex A. Froehner clones were selected through genetic parameters under an irrigated system, without agrochemi

4. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

5. Characterization of incidence and development of pests and deseases in coffee agroecosystems under different managements / Caracterização da incidência e evolução de pragas e doenças em agroecossistemas cafeeiros sob diferentes manejos
This research aims to characterize the incidence and development of major pests and diseases of coffee in agroecosystems under conventional, organicmineral, organic and agroforestry managements in two municipalities in the southern Minas Gerais State: Machado and Poço Fundo. It was carried out monthly monitoring of the leaf-miner (Leucoptera coffeella), bor

6. Avaliação de produtos alternativos na sanidade do cafeeiro (coffea arabica L.)
O estudo teve por objetivo, avaliar a eficiência de produtos não convencionais e utilizados em sistemas orgânicos de café, no controle do bicho mineiro Leucoptera coffeella (Guérin-Mèneville, 1942) (Lepidoptera- Lyonetiidae), da ferrugem do cafeeiro Hemileia vastatrix (Berkeley &Broome), e da cercosporiose Cercospora coffeicola (Berkeley &Cooke). Foram

7. Bicho-mineiro do cafeeiro: anÃlise da digestÃo e inibiÃÃo de tripsina por extratos de folhas de mamona. / Coffee leaf miner: Digestion and trypsin inhibition using castor beam leaves extracts.
Coffee is a crop of great social and economic importance to Brazil and its production is affected by a number of pests and diseases. One of those pests is the coffee leaf miner, Leucoptera coffeella (GuÃrin-MÃneville, 1842) (Lepidoptera: Lyonetiidae) which can cause great losses in production. The forms of controlling the coffee leaf miner known and utiliz

8. Silicon as a potentiater of the activity of enzymes related to the defense to rust in coffee and soybean plants / Silício como potencializador da atividade de enzimas de defesa à ferrugem em plantas de café e soja
The coffee leaf rust (Hemileia vastatrix) and asian soybean rust (Phakopsora pachyrhizi) can significantly reduce yield, respectively, on coffee and soybean crops. Silicon (Si) is a beneficial element to plants because it increases host resistance to pests and diseases. In response to infection by pathogens, plants activate many mechanisms of defense such as

9. Purificação da enzima polifenoloxidase do cafeeiro, sua relação com resistencia a pragas e o controle da sintese de seu principal substrato, o acido clorogenico / Coffee polyphenoloxidase purification, its relation with plague resistance and synthesis control of its maim substrate, chlorogenic acid
Polyphenoloxidase - PPO (EC 1.14.18.1 ou EC 1.10.3.2) is an enzyme with broad distribution among plants and catalyzes the hydroxylation of monophenols to o-diphenols and the oxidation of these to o-diquinones. Its function on plants has been related to defense mechanisms against pathogens and plagues. 5-Caffeoylquinic acid, also known as chlorogenic acid (CG

10. Environmental vulnerability analysis of the main recommended pesticides for cotton, rice, coffee, sugar cane, citrus, corn and soybean production systems / Analise da vulnerabilidade ambiental aos principais pesticidas recomendados para os sistemas de produção de algodão, arroz, café, cana-de-açucar, citros, milho e soja
The utilization of pesticides in agriculture is a necessary practice to control pests, diseases or weeds to reach an excellent index of productivity and get attend the increasing necessity of food. Some of this pesticides applied, show dangerous physical-chemical proprieties to the environmental and health human. Many times it happen because we haven?t enoug

11. Melhoramento da qualidade do cafe brasileiro : influencia de sistemas de produção e processamento sobre algumas caracteristicas da bebida
On the international coffee market, brazilian arabica coffee is described as having unpleasant characteristics of the beverage, normally relating the descriptions of "hardness" or "phenolic, chemical, rio" flavours to the dry method of green coffee bean processing. The so-called "depulped beans" or processed by the wet method are generally recognized as poss
