“…In the first crop cycle, 28.9% of the tested genotypes presented a high resistance reaction to MRRVD ('RZ 34292','RZ 34130','Massaï', Pathogenicity studies for M. cannonballus have been previously carried out in different countries, but no resistant or tolerant genotype was found for melon. However, the variation in the degree of resistance found among the genotypes in the present research, corroborates with the literature (WOLFF, 1995;MARTYN;MILLER, 1996;SALES et al, 2002;ANDRADE et al, 2005;EDELSTEIN et al, 2017).…”

“…Countless control strategies against this disease have been tested, either in isolation or in association with others, but, none of them showed efficiency. However, they can be effective when sustainable measures are incorporated (MEDEIROS et al, 2008), such as the use of green fertilisation (SALES JÚNIOR et al, 2017), post-harvest residue destruction (RADEWALD; FERRIN; STANGHELLINI, 2004), chemical control (PIVONIA et al, 2010), application of essential oils (FERNANDES et al, 2015;AWAD, 2016), use of plant-growth-promoting bacteria (ANTONELLI et al, 2013), use of biocontrol agents (ALEANDRI et al, 2015) and grafting on hybrid rootstocks of Cucurbita (AL-MAWAALI et al, 2016;EDELSTEIN et al, 2017).…”

REACTION OF MELON GENOTYPES TO THE ROOT´S ROT CAUSED BY Monosporascus

et al. 2019

Monosporascus root rot and vine decline (MRRVD) is an important disease in the melon crop in Brazil. In our research, we evaluated the reaction of 45 melon genotypes to M. cannonballus in two successive cropping seasons in a greenhouse. Melon seedlings were transplanted into naturally infested soil. The evaluation of the genotypes was performed after 55 days, using a score scale to group each genotype into one of five classes and to calculate the disease severity index. None of the genotypes showed an immune reaction to M. cannonballus, regardless of the season. In the first cycle, only 28.9% ('AF 464', 'Auraprince', 'DRG 2278', 'Estoril', 'Guaporé', 'Kousto', 'Mabel', 'Magisto', 'Massaï', 'Nectar', '8530', 'RZ 34130' and 'RZ 34292') had a similar reaction to the high resistance to the MRRVD. Most genotypes (66.7%) behaved as moderately resistant while 4.4% were susceptible and none were highly susceptible. Conversely, in the second cycle, no genotype showed a reaction similar to high resistance while 42.2% behaved as moderately resistant, 48.9% as susceptible, and 8.9% as highly susceptible. The severity levels ranged from 7.5 to 60% and 27.5 to 92.5% for the first and second cycles, respectively. The genotypes 'DRG 2278', 'Estoril', 'Guaporé', 'Kousto', 'Mabel', 'Massaï', 'RZ 34130' and 'RZ 34292' were identified as highly resistant and moderately resistant in the first and second cycles of cultivation, respectively. Therefore, these genotypes are promising sources of resistance to M. cannonballus and should be preferred in commercial fields infested with the pathogen.

“…The results indicated that plant growth traits are affected by grafting and Argentario and Nun 9075 commercial rootstocks performed better that PI 293341 and the control. The results of this study in terms of main stem diameter agree with the results reported by Edelstein et al (2017), using interspecific Cucurbita hybrid rootstocks. In considering the length of the main stem, the results are higher than those reported by Alan et al (2007), who used different commercial Cucurbita hybrid (TZ 148 and RS 841) and L. siceraria rootstocks, and Alan et al (2017), who used Lagenaria and commercial ('Shintoza F90' and 'Obez') rootstocks.…”

The aim of this study was to evaluate different rootstocks for improving triploid seed production of the dessert watermelon, Citrullus lanatus. This 2-year study was conducted at two locations, in open fields at Antalya and Adana, Turkey, during the 2016 and 2017 growing seasons. The tetraploid watermelon line 'ST 101' was used as the female parent scion and the diploid line 'WL 92' as the male parent. Both parental lines were grafted onto three different rootstocks to determine the effect of grafting on seed yield and quality of triploid watermelon. Nun 9075, a Cucurbita interspecific hybrid (Cucurbita maxima × Cucurbita moschata), Argentario (Lagenaria siceraria), and citron watermelon PI 296341 (Citrullus amarus) were used as rootstocks. Nongrafted ST 101 and WL 92 were also crossed to be used as controls. The graft combinations and controls were compared for performance as measured by length, diameter and number of nodes of main stem, total yield, mean fruit weight, fruit length, fruit diameter, seed yield, number of seed per fruit, weight of 1000 seeds, seed germination and emergence percentage, days to germination and emergence, and seed coat and embryo weight ratio. Nun 9075/ST 101 and Argentario/ST 101 graft combinations resulted in longer main stems; increased total yield; heavier, longer, and wider fruits; and higher seed yield and number of seeds per fruit as compared to PI 296341/ST 101 graft combination and the controls in both locations and years.

“…In modern agriculture, cucurbits are commonly grafted either on intraspecific rootstocks (Cohen, Burger, Horev, & Koren, 2007) or interspecific rootstocks (Lee & Oda, 2010). Importantly, cucurbit grafting could reduce viral infection from contaminated soil (Cohen et al, 2007; Cohen, Dombrovsky, & Louws, 2017; Edelstein, Cohen, Gur, et al, 2017; Smith et al, 2018). However, grafting knives could mediate viral secondary spread.…”

Cucumber green mottle mosaic virus (CGMMV) assigned to the genus Tobamovirus is considered a major disease cause of cucurbits worldwide. A primary route for CGMMV disease spread is via mechanical contact. The virus is highly stable and adheres to various agricultural equipment. In the current study, we examined means to inactivate the virus and reduce disease spread via planting equipment and supplies using various chemicals. We have found that incubations of CGMMV‐infected cucumber plant extracts with MENNO‐Florades 2%, Virocid 3% or Green Up D 20% inactivated the virus and prevented disease spread in a biological assay. Stabilised chlorine formulation (KlorBac), which has the active ingredient troclosene‐sodium (sodium dichloroisocyanurate, SDIC) at 2,000 ppm, was efficient in disinfecting CGMMV‐contaminated grafting knives in 2 s. Similarly, immersing virus contaminated grafting knives for 2 s in 20% (wt/vol) non‐fat milk powder reduced infectivity of the contaminated knives. CGMMV‐contaminated nursery sowing trays could constitute a primary infectious viral source transmitted via irrigation water. CGMMV‐contaminated sowing trays immersed in KlorBac 2,000 ppm or active oxygen (Huwa‐San TR‐50) 1%, were efficiently disinfected. Interestingly, hydrophobic insulation of the CGMMV‐contaminated trays using dry silicone layers reduced initiation of the viral primary infection in CGMMV‐contaminated new sowing trays but was less efficient in CGMMV‐contaminated re‐used trays. Importantly, Septadine (0.5% chlorhexidine gluconate) was not effective in disinfection of grafting knives. Notably, CGMMV‐infected cucumber plant extract incubated with 20% (wt/vol) non‐fat milk powder was refractory to the milk suggesting that virus release from surfaces did not necessarily involve virus inactivation.
