ABSTRACT The interaction between Meloidogyne and Fusarium can alter the resistance behavior of passion fruit genotypes. The study was aimed to evaluate the reaction of genotypes of Passiflora spp. to Meloidogyne incognita race 3 (Mi)-Fusarium solani (Fs) complex. The assay was carried using RBD in the factorial arrangement: 10 genotypes (BRS-SC, M-19-UFV, P. alata, P. nitida, P. giberti, P.setacea, P. mucronata, P. murifolia, P. cincinnata, P. ligularis) x 3 treatments (Mi, Mi+Fs, Fs). After 180 days of planting the reaction to Mi was determined by RF (Pi/Pf) and to Fs by lesions size in roots and stems. According to the criteria of Oostenbrink and Moura and Regis, BRS-SC, M-19-UFV. P. alata and P. cincinnata behaved as resistant and P. giberti as susceptible. According to the Taylor and Sasser, BRS-SC, M-19-UFV, P. alata, P. cincinnata and P. giberti behaved as resistant, moderately resistant, moderately suscetible and susceptible, respectively. Lower percentage of plants with symtoms of Fs was found in P. mucronata, P. nitida, P. setacea, P. cincinnata and M-19-UFV In the presence of both pathogens, M-19-UFV, P. alata and P. nitida were those with larger lesion. In the presence de Fs, BRS-SC, P. alata, P. cincinnata and P. ligularis showed the largest lesions.

Two soybean (Glycine max) cultivars were used in this study, Ocepar 4, rated as moderately resistant to Meloidogyne incognita race 3 but susceptible to M. javanica, and 'BR 16', susceptible to both nematodes. The effect of nematodes infection on the uptake and transport of N, P and Ca to the shoot was studied in plants growing in a split root system. The upper half was inoculated with 0, 3,000, 9,000 or 27,000 eggs/plant while the lower half received 15N, 32P or 45Ca. Infected plants showed an increase of root but a decrease of shoot mass with increasing inoculum levels. In general, total endogenous nutrients increased in the roots and tended to decrease in the shoots with increasing inoculum levels. When concentrations were calculated, there was an increase in the three nutrients in the roots, and an increase of Ca but no significant variation of N and P was observed in the shoots. The total amount of 15N in the roots increased at the highest inoculum levels but 32P and 45Ca decreased. In the shoots there was a reduction of 32P and 45Ca. The specific concentrations of the labelled nutrients (abundance or radioactivity/tissue mass) also showed a decrease of 32P and 45Ca in the shoots and roots of infected plants and an increase of 15N in the shoots. Considering that overall nutrient concentrations reflect cumulative nutrient uptake and the data from labelled elements gave information at a specific moment of the infection, thus nematodes do interfere with nutrient uptake and translocation.

Root knot nematodes (<italic>Meloidogyne</italic> spp.) cause immense yield losses in crops throughout the world. Use of resistant germplasms of plants limits the root knot nematode damages. In this study, 87 common bean (<italic>Phaseoulus vulgaris</italic> L.) genotypes were screened against the root knot nematode, <italic>Meloidogyne incognita</italic> to determine the resistance response under growth chamber conditions in Turkey. <italic>P. vulgaris</italic> genotypes were evaluated based on resistance index (RI); root galling severity and nematode egg mass production on a 1-9 scale. The nematode negatively influenced the growth (fresh weight) of bean genotypes. At the completion of the study, 13 bean genotypes were found as immune (Sehirali), highly resistant (TR42164, Seleksiyon 5, Seker Fasulye, Fas-Agadir-Suk-1) and moderately resistant (Acik Badem, TR68587, TR43477, TR53827, TR28018, Gülnar-3, Siyah Fasulye, Kibris Amerikan) against <italic>M. incognita</italic> thus suggesting the use of such genotypes in breeding studies as a parental material to develop the root knot nematode resistant cultivars.

Screening passion fruit genotypes to target resistance to scab and bacterial blight may play an important role in reducing the application of chemical products and losses caused by the diseases. It is likely that resistant genotypes may be found in ongoing breeding programs targeting production traits. Thus, the objective of this work was to evaluate the host status of eighteen passion fruit genotypes from the Breeding Program of the Universidade Federal de Viçosa (CRP 01-12 to CRP 16-12, CRP 19-12 and CRP 20-12) and two cultivars (FB 200 Yellow Master and FB 300 Araguari) of yellow passion fruit to the scab (Cladosporium herbarum) and bacterial blight (Xanthomonas axonopodis pv. passiflorae). The fungus and the bacterium were artificially inoculated on wounded leaves at the concentrations of 1 x 106 spores mL-1 and 1 x 108 cfu mL-1. Scab incidence and severity were assessed at 7, 14, 21 and 31 days after inoculation (DAI); whereas the bacterial blight evaluations were performed at 10, 20, 28 and 44 DAI. The genotypes CRP 01-12 to CRP 16-12 and CRP 19-12 are moderately resistant to scab. The genotype 20-12 and the FB 200 Yellow Master cultivar are susceptible to the fungus. All genotypes are highly susceptible to bacterial blight.

Pepper yellowing disease is one of the most important disease of pepper causing the decrease of pepper production. This research was conducted in the screen house and laboratory to determine the major causal agent of leaf yellowing disease of pepper. Meloidogyne incognita and Fusarium solani were isolated from pepper plantation in West Kalimantan. Pepper seedlings Natar 1 cultivars were planted in sterilized soil collected from pepper plantation in Bengkayang, West Kalimantan. Five months-old seedling were inoculated with M. incognita (1000 larvae of 2nd stadium/plant) and F. solani (50 ml of spore suspension with spore density of 106 spore/ml) in several combinations of time inoculation, i.e., F. solani  and then M. incognita, M. incognita and then F. solani, M. incognita together with F. solani, M. incognita only, and F. solani only. The parameters observed were the development of leaf yellowing disease every weeks for five months. The number of gall, and population M. incognita were observed at the end of the observation. The result showed that when M. incognita was inoculated  to the roots followed by F. solani, the disease severity and the percentage of plant diseases were higher than those which were infected with F. solani or M. incognita alone. The higher population densities of M. incognita and a number of root gall, had observed on plants inoculated by M. incognita combined with F. solani than plants inoculated by M. incognita and F. solani alone. Interaction between M. incognita and F. solani as caused of leaf yellowing disease of pepper was synergistic reaction. IntisariPenyakit kuning lada merupakan salah satu penyakit penting pada lada yang mengakibatkan terjadinya penurunan produksi lada di Indonesia.

Fruit fly (Bactrocera tau) is the most destructive pest on some fruits in Indonesia. Monitoring of the pest population is essential as one of the procedures in the IPM concept. The study aimed to investigate the seasonal fluctuation of adult males of B. tau and their damage on passion fruits in relation to abiotic factors. The research was done by a survey method on three plots of passion fruit orchards in Alahan Panjang, West Sumatra, Indonesia from March to December 2005. In plot 1 the farmer practiced sanitation by removing damaged fruits and weeds from the orchard. In the plots 2 and 3 no sanitation was practiced. Each plot was 1 ha in size. The parameters observed were density of adult male B. tau and climatic factors (rainfall per day, number of rainy days, and average day temperature). Empty mineral water bottle traps were used to catch adult males of B. tau. Each plot had 16 traps set up with cue lure as fruit fly attractant. Each trap was baited with 3 ml cue lure on a cotton wick (1 cm diameter). The cotton wick was rebaited at 2-week intervals. The traps were placed on host plants about 1.5 m above the ground. Trapped flies were collected every two weeks and counted. The data were analyzed by correlation analysis. The results revealed that the number of male B. tau<br />in three orchards showed a similar fluctuation during the study period with a major peak in July. The lower numbers of flies captured in plot 1 (with sanitation) compared to the two other plots (without sanitation) were consistent with a lower percentage of damaged fruits in the plot 1 compared to the other two. The percentage of damaged fruits gradually decreased over time to about 20% in plot 1 which is lower than that in the other two<br />plots (30-40%). The number of fruit flies captured with cue lure baited traps correlated positively with all three abiotic factors studied. The seasonal fluctuation of the fruit fly population and the damage to the fruits are necessary to be studied as a procedure<br />in IPM for controlling B. tau.

Fourteen cultivars of cucumber were screened for their resistance to the Southern root-knot nematode, Meloidogyne incognita (Kofoid and White) Chitwood in an in planta experiment. The pots were maintained in greenhouse with CRD for 50 days after inoculation. The cultivar DS92-05 induced significant mortality and was rated “moderately resistant (MR)”. This cultivar showed increase in plant growth parameters including vine length. The cultivars DS92-06, Laghman, Sultan and Desitype were moderately susceptible (MS). The cultivar Rehan and DS96-299 were rated susceptible (S) whereas DS97-299, Chaiya, Beitalpha, Alto, DS92-04 and Local were rated as highly susceptible (HS). DS92-05 is thus promising for sustainable agriculture, specially in those areas with high population density of Southern Root knot nematode.

Drinks composed of more than one fruit are a trend in the national and international market, presenting advantages such as greater nutritional value and the development of new flavors. So, the objective was to elaborate six formulations of mixed nectar of mango and passion fruit, varying the percentage of each pulp and soluble solids content, as well as evaluating its physicochemical, microbiological, sensorial and stability properties. The nectars were prepared by the hot fill process and packed in 500 ml glass bottles, and then submitted to the analyzes. The nectars presented pH between 2.86±0.05 and 3.33±0.15, soluble solids of 10.00 to 14.83 ºBrix, acidity of 0.59 to 0.78g acid citric/100g nectar, and vitamin C from 15.36 to 33.66 mg/100g. The microbiological analyzes presented values according to the current legislation. The formulations were within the sensory acceptance zone for the tasters, with a balance in the evaluated attributes. F4 (10g of passion fruit and 20g of mango) was chosen among the formulations due to greater acceptance and use of a lower percentage of passion fruit, reducing the cost of the product. In relation to the stability, none of the sensorial attributes presented differences in the interval of 150 days, however, for the physical-chemical attributes, it was observed difference in pH, total acidity, vitamin C and total soluble solids. Therefore, it is necessary to better assess the physical and chemical characteristics, with the intention of increasing the nutritional index of the product.

Root-knot nematodes have become a grave menace to the lucrative production of cucumber throughout the world. These nematodes are mainly controlled by applying nematicides, but their use is often associated with hazards. Alternatively, the use of nematode resistant cultivars is considered to be innocuous and economically feasible. For their fitness as nematode-suppressive crops, the reduction in growth and yield parameters of these cultivars must be assessed. As there is little documented data about the effects of Meloidogyne incognita on the damage of cucumber, therefore, in the present study, the effects of M. incognita were evaluated on growth and yield parameters of fifteen cucumber cultivars. M. incognita significantly negatively affected the growth and yield parameters of all the cucumber cultivars. Shoot and root lengths and shoot weights of all the cultivars were significantly reduced as a result of nematode infection. Maximum reductions in these parameters were recorded in highly susceptible cultivars followed by susceptible ones, while the reductions were minimal in resistant followed by moderately resistant cultivars. On the contrary, the infection by M. incognita resulted in an increase in root weights of all the cultivars. The increase was found to be the maximum in highly susceptible cultivars followed by susceptible and moderately susceptible cultivars. Likewise, the minimum increase was observed in the resistant cultivars followed by moderately resistant cultivars. Similarly, significant variations in yield parameters among fifteen cucumber cultivars were also recorded as a result of M. incognita infection. In the case of highly susceptible cultivars, the reductions in yield parameters were maximum, whereas the reductions in resistant and moderately resistant cultivars were found to be minimum. As cultivars Long Green, Marketmore, Pioneer-II, Dynasty and Summer Green experienced no significant damage compared to susceptible cucumber cultivars and therefore, they are approved for cultivation in nematode infested soils.
