“…The plates were incubated for 3 days at 25°C in a growth chamber (12 h photoperiod). Pure cultures were obtained by transfer of a single sclerotium and maintained on PDA slants at 4°C for 2-4 weeks (Christian et al 2001;Li et al 2003;Sarma et al 2007). In all, a total of 1786 isolates were collected throughout Jiangsu Province.…”

Carbendazim (MBC) was widely used to control Sclerotinia stem rot routinely during the 1980s in China, but development of MBC resistance in the causal agent Sclerotinia sclerotiorum led to control failures of this disease. In this study it was found that the MBC resistance in S. sclerotiorum populations was widespread throughout Jiangsu Province with a resistance frequency of 29.54% in the 1786 collected isolates during the growing seasons of 2006 to 2008. The resistance frequencies differed among sampled cities, ranging from 3.1% to 54.9%. The field MBCresistant isolates showed comparable mycelial growth, sclerotia production and pathogenicity to the wild-type sensitive isolates, which suggested that the field MBC-resistant isolates might have sufficient parasitic fitness to compete with the field MBC-sensitive isolates in the field. In the in vitro sensitivity test, boscalid showed greater activity against S. sclerotiorum than dicarboximide fungicides (dimethachlon, iprodione and procymidone).The treatment 50% boscalid (WG) 125 g a.i. ha −1 was comparable in efficacy to the treatment 50% iprodione (WP) 600 g a.i. ha −1 , and better than other treatments of 6% dimethachlon (WP) 690 g a.i. ha −1 and 50% procymidone (WP) 337.5 g a.i. ha −1 , whereas MBC failed to control Sclerotinia stem rot (control efficacy only 16.0%). The most active agent for controlling Sclerotinia stem rot was boscalid in our study.

“…Fungitoxicity does not seem to explain reduction in plant mortality as both the chemicals failed to check growth of S. rolfsii on artificial medium at the test concentrations. Reduction in plant mortality by these two chemicals thus may be due to induction of resistance in the host as reported recently by Sarma et al (2007). Both ZnSO 4 and oxalic acid at low concentrations induce activities of the phenylpropanoid pathway leading to biosynthesis of antifungal phenolic compounds.…”

“…Based on prior knowledge (Sarma et al 2007) and screening by the poisoned food technique, ZnSO 4 and oxalic acid were selected for this experiment, because these chemicals showed no in vitro fungal toxicity at their effective concentration (10 À4 mM and 4 mM, respectively). Both the chemicals were pure grade (Merck, Germany).…”

“…Recently, some non-conventional chemicals have been recognized as potent systemic acquired resistance (SAR) activators that do not have antimicrobial properties, but instead increase crop resistance to pathogens by activating the SAR signal transduction pathway in several plant species. There are several records revealing induction of resistance in hosts against their pathogens by treatment with various non-conventional chemicals and the effect mostly appears to be mediated through the host (Sinha 1984;Lazarovits 1988;Sarkar and Sinha 1992;Sinha 1995;Bhatacharya and Roy 1998;Sarma et al 2007).…”

Two non-conventional chemicals, ZnSO 4 (10 À4 mM) and oxalic acid (4 mM) were tested (alone as well as in combination with seeds bacterized with Pseudomonas syringae strain PUR46 and vermicompost substitution in the potting soil), for their ability to suppress collar rot of chickpea (Cicer arietinum) caused by Sclerotium rolfsii under greenhouse conditions. ZnSO 4 and oxalic acid were applied as pre-inoculation foliar spray on chickpea and subsequently challenged with S. rolfsii. Both the chemicals provided significant protection to chickpea compared to control (100% plant mortality) when used alone as well as in combination with PUR46 and vermicompost. However, ZnSO 4 was more effective than oxalic acid against S. rolfsii. Amongst the treatments tried, plant mortality was least when ZnSO 4 was used in combination with seed bacterization with PUR46 and 25% vermicompost substitution. The findings indicate the utility of integration of the above factors in managing collar rot efficiently.

“…Agrawal (1999) reported that ZnSO 4 sprayed plants showed maximum grain yield and 1000-grain weight in maize as compared to check. Foliar sprays of Zinc Sulpate at 10 −3 mmol to chickpea (Cicer arietinum) and subsequently challenged against Sclerotinia sclerotiorum, causing stem rot in chickpea gave the best result and only 13.6% mortality was recorded after 28 days as compared to 100% in the control (Sarma et al, 2007). In the present study the treatment CaSO 4 at 1.0% significantly increased the number of primary branches, number of secondary branches, seed yield/plant and total yield/ha (Table 6).…”

Abstract:The present investigation was done to evaluate the effect of different concentrations of five eco-friendly chemicals in vitro and in vivo, on the management of alternaria blight and yield attributes in Indian mustard (Brassica juncea cv. Varuna). Out of five eco-friendly chemicals, K 2 SO 4 1000 ppm (64.28%) followed by ZnSO 4 1000 ppm (63.88%) showed maximum inhibition of mycelial growth in comparison to check. 0.5% concentration of KCl (57.06%) followed by CaSO 4 (59.50%) and K 2 SO 4 (62.20%) showed significantly maximum effect on spore germination in comparison to check (74.60%). Spore intensity significantly increased by all the treatments except CaSO 4 at 0.5% (40.18%) followed by K 2 SO 4 at 0.5% (29.86%) and ZnSO 4 0.75% (5.11% reduction) in comparison to check. The significantly minimum disease index on leaf over check was found by foliar spray of CaSO 4 at 0.5% (23.58%) followed by CaSO 4 at 1.5% (24.00%) and Na 2 B 4 O 7 .10H 2 O at 1.5% (24.08%). Na 2 B 4 O 7 .10H 2 O at 0.75% showed significantly lowest disease index (23.91%) on pod followed by K 2 SO 4 at 1.5% (25.75%) and KCl at 1.5% (26.00%) in comparison to check. CaSO 4 at 1.0% showed maximum number of primary branches (7.00), number of secondary branches (13.00) and total yield/ha (1917.30 kg/ha) in comparison to check. The results obtained from the present study suggested that K 2 SO 4 showed maximum in vitro effect on Alternaria brassicae and CaSO 4 and Na 2 B 4 O 7 .10H 2 O are providing maximum reduction of disease and increase in seed yield/ha that leads to efficient alternaria blight disease management strategies in field condition. These eco-friendly chemicals can protect the crops from alternaria blight diseases and increase the production and productivity of the Indian mustard crop.
