Considerable Loss

The sponge gourd (Luffa cylindrica Roem) is one of the most popular vegetable. There are a number of diseases like Powdery mildew, Downey mildew, Anthracnose, Fusarium root rot, Cercospora leaf spot, Soft rot and cottony fruit rot, they cause considerable loss to sponge gourd in term of quality and quantity both. During the survey in the year 2015-16, it was found that among all the diseases cottony fruit rot caused by Pythium aphanidermatum was a very destructive disease of this important crop. To manage the loss of yield due to this disease twelve fungicide and eight bioagents were evaluate against the pathogen (in-vitro) in biocontrol lab, Deptt. of plant pathology during 2015-16. Among all the tried fungicide, Master, Propioconazole and Tubuconazole were most effective for inhibition of radial growth of Pythium aphanidermatum and it was recorded no growth. In case of bioagents Trichoderma koningii and Trichoderma harzianum wear most effective for inhibition of test pathogen and it was 15.33mm and 16.66mm respectively.

Luffa sponge (smooth gourd) and bitter gourds (bitter melon) are specialty vegetables grown in the U.S. on a small scale for select markets. Luffa gourds are also grown for sponges. In Sept. 2014, heavy rainfall resulted in rot of >50% of bitter gourd and >25% on sponge gourd in a field in Charleston, SC. The microbe causing the fruit rot was identified using microscopy and molecular tools. Prior to this study it was not known if this microbe could cause fruit rot of bitter gourd. This knowledge will be useful to suggest management strategies. Accepted for publication 17 March 2015. Published 6 May 2015.

The effect of various carrier formulations of Bacillus subtilis and Pseudomonas putida were tested on germination, growth, and yield of lettuce and cucumber crops in the presence of Pythium aphanidermatum and Fusarium oxysporum f.sp. cucurbitacearum, respectively. Survival of B. subtilis and P. putida in various carriers under refrigeration (about 0°C) and at room temperature (about 22°C) was also studied. In all carrier formulations, B. subtilis strain BACT-0 survived up to 45 days. After 45 days of storage at room temperature (about 22°C), populations B. subtilis strain BACT-0 were significantly higher in vermiculite, kaolin, and bacterial broth carriers compared with other carriers. Populations of P. putida were significantly higher in vermiculite, peat moss, wheat bran, and bacterial broth than in other carriers when stored either under refrigeration (about 0°C) or at room temperature (about 22°C) for 15 or 45 days. Germination of lettuce seed was not affected in vermiculite, talc, kaolin, and peat moss carriers, but germination was significantly reduced in alginate and bacterial broth carriers of B. subtilis compared to the non-treated control. Germination of cucumber seed was not affected by any of the carriers. Significantly higher fresh lettuce and root weights were observed in vermiculite and kaolin carriers of B. subtilis compared with P. aphanidermatum-inoculated control plants. Lettuce treated with vermiculite, and kaolin carriers of B. subtilis, or non-inoculated control lettuce plants had significantly lower root rot ratings than talc, peat moss, bacterial broth, and P. aphanidermatum-inoculated control plants. Growth and yield of cucumber plants were significantly higher in vermiculite-based carrier of P. putida than the other carriers and Fusarium oxysporum f.sp. cucurbitacearum-inoculated plants.Key words: Bacillus subtilis, Pseudomonas putida, Fusarium oxysporum f.sp. cucurbitacearum, Pythium aphanidermatum, talc, vermiculite, alginate, kaolin, peat moss, wheat bran, oat bran.
