“…Another associated problem is nematode infestation. Cantu et al (2009) mentioned that heavy infestations at the beginning of the crop may result in the death of the seedlings in the field and the production of the surviving plants become strongly affected in terms of both quantity and quality. Grafting technology can reduce the attack of soil pathogens and in turn makes plant adaptation to soil and climatic conditions possible.…”

Atualmente, o tomate é uma das culturas mais cultivadas no mundo, com o maior valor econômico, aumentando sua demanda e, assim, sua expansão, produção e comercialização. A cultura do tomate é suscetível ao ataque de patógenos com consequências devastadoras no declínio da produtividade de 50 para 100%. Por esta razão, novos métodos de produção são propostos, como o uso de porta-enxertos selvagens, que possuem alta variabilidade genética e genes responsáveis pela resistência a fungos, bactérias, vírus e nematoides. O objetivo deste trabalho foi avaliar o efeito do enxerto de cultivares comerciais de tomateiro sobre genótipos de tomateiro em produtividade e qualidade de frutos. O experimento foi organizado em delineamento inteiramente casualizado com quatro repetições. A unidade experimental consistiu em quatro plantas, espaçadas a 0,9 m entre linhas (canais), 0,30 m entre linhas duplas e 0,4 m entre plantas. Os tratamentos consistiram da combinação dos seguintes fatores: três porta-enxertos promissores (IAC391, IAC426 e LA2076), dois enxertos comerciais (Calima e Torrano), dois métodos de enxertia (fenda e inglês simples) e dois controles comerciais não enxertados. Os componentes de rendimento, teor de sólidos solúveis, porcentagem de qualidade dos frutos e peso médio dos frutos foram avaliados. O IAC391 foi o porta-enxerto mais promissor, alcançando produções semelhantes às dos controles. O método de enxertia de fenda atingiu uma taxa de sucesso de 98,3%. O enxerto comercial Torrano se destacou por alcançar os maiores rendimentos.Palavras-chave: fenda; inglês simples; Torrano; Calima; porta enxerto. ABSTRACT RESUMODevelopment, production, and quality of 'Chonto' type tomato grafted on cherry tomato introductions 1 Currently, tomato is one of the most cultivated crops worldwide, with the highest economic value, increasing its demand and, thus, its expansion, production, and trade. The tomato crop is susceptible to attack of pathogens with devastating consequences on the decline in yields from 50 to 100%. For this reason, new production methods are proposed such as grafting in wild rootstocks, which have high genetic variability and genes responsible for resistance to fungi, bacteria, viruses, and nematodes. The aim of this study was to evaluate the effect of grafting commercial tomato cultivars onto cherry tomato genotypes on yield and fruit quality. The experiment was arranged in a completely randomized design with four replications. The experimental unit consisted of four plants. spaced at 0.9 m between rows (channels), 0.30 m between double rows, and 0.4 m between plants. The treatments consisted of the combination of the following factors: three promising rootstocks (IAC391, IAC426, and LA2076), two commercial scions (Calima and Torrano), two grafting methods (cleft and splice), and two ungrafted commercial controls. Yield components, soluble solids content, percentage of fruit quality, and average fruit weight were evaluated. IAC391 was the most promising rootstock, reaching productions similar to those of th...

Nematodes are obligatory parasites that compromise agricultural production worldwide. The use of alternative methods to replace the chemical pesticides in the control of this pest is increasingly growing, due to its pollution to the environment. In order to evaluate the biocidal effect of plant extracts, combinations of extracts of Neem (Azadirachta indica), croton (Croton campestris) and manioc (Manihot esculenta) were used in the control of root knot nematode, Meloidogyne incognita in tomato plants. The extracts were obtained from dried leaves and exposed to cold extraction with ethanol, under reduced pressure, with the aid of rotaevaporador. The application of the treatments took place 72 h after inoculation of suspension with 4,000 eggs/juveniles in the region of the root. Extracts from croton and cassava promoted plant height in the order of 26.75 and 34.50%, respectively; while neem extract inhibited the numbers of nematode juveniles in the root (51.34%), croton (50.85%), and manioc (41.31%). As for juveniles in the soil, only 47.33% was reduced in cassava. However, the mix of the extracts potentiated the effects on improvement of growth parameters and reduction of nematode parasitism.
