Aloe vera is a valuable medicinal crop of the world. It suffers from several diseases but among them alternaria leaf spot and dry rot is most serious fungal disease which effects the commercial production and quality losses to Aloe vera. A survey was conducted to estimate the prevalence of dry rot disease in different nurseries located in urban areas of Faisalabad. During this survey maximum disease incidence was recorded in Horti club nursery (100%) and minimum disease incidence recorded at Faiz baho nursery and Qadir baksh form (13.8%). Among in-vitro tested fungicides Score gives maximum mycelial growth inhibition (89.5%) and maximum disease control (17.7%) as compared to control and other tested chemicals. Among in-vitro tested plant extracts Neem gives maximum mycelial growth inhabitation (41.2%) and in green house gives 14.2% disease control. Out of four tested fungicides and plant extracts Score and Neem gives best results against A. alternata mycelial growth and disease control.

“…Antimicrobial and antifungal activities have been ascribed to extracts of C. prostrata, D. scandens, H. suaveolens, S. jamaicensis and A. conyzoides by several workers in many studies. 44,45,46 32,47,48 Plant secondary metabolites interfere; disrupt or inhibit biologically active sites of enzymes, molecules and organelles of hosts' tissues or essential processes of target pathogens. 49,50 The observed inhibitions against spore germination and radial growth of the test fungus in this study may have been due to presence and ability of phytochemicals in the extracts to disrupt or interfere with one or more processes or enzymes of the target fungus.…”

“…Findings in this study whereby extracts of the test plants strongly inhibited spore germination and radial growth of A. batiticola is in agreement with the reports of previous workers, who found aqueous and ethanol extracts of some tropical plants to strongly or completely inhibit these parameters in Alternaria tenuissima and A. alternata in vitro. 47,51 All the plant tissue extracts used in this study reduced to varying degrees, leaf and stem blight development, spread and severity on the treated sweet potato (Table 2). Plants treated with mancozeb had the lowest incidence (18.92%) and severity score (1.18) of leaf and stem blight, which were significantly higher than effects recorded for these parameters from all other treatments on the test crop.…”

Leaf and stem blight (Alternaria bataticola) is one of the principal constraints to effective sweet potato production in many parts of the tropics. This work assessed the potentials of extracts of some indigenous plants to control the disease in vitro and under field conditions. The treatments comprised 20% aqueous extracts of Stachyterpheta jamaicensis, Cyathula prostrata, Diodia scandens, Ageratum conyzoides and Hyptis suaveolens, mancozeb and water (control). The experiment was set up in RCBD with 3 replicates. The results showed that all the extracts inhibited spore germination (65.08-78.71%) and radial growth (77.54-92.01%) of the pathogen in vitro, though these were statistically inferior (P>0.05) to 82.06 and 95.25% recorded for mancozeb respectively. The extracts of the indigenous flora also performed well in inhibiting the disease in vivo. Mancozeb gave the highest reduction of blight incidence (18.92%) and severity (1.18) on the treated crop, however the values (20.11-30.06%) and 1.24-2.79) of the indigenous flora extracts were significantly (P<0.05) superior to the control which had 81.35% and 7.47 for the respective test parameters. The high minimization of disease incidence and severity in mancozeb and extracts treated plots compared to the control may have accounted for the higher yield of root (6.07-10.65 tha -1 ) and haulm (1.37-2.51 tha -1 ) than (3.01 tha -1 and 0.87 tha -1 ) obtained for the control respectively. This study showed that smallholder farmers of sweet potato can use aqueous extracts of S. jamaicensis, C. prostrata and H. suaveolens to keep leaf and stem blight at bay and increase the productivity of the crop.

“…Plant extract is recently advocated by several researches, as a potential control method of plant diseases (Belabid et al, 2010). Many plant extracts and essential oils have been reported to possess antimicrobial properties (Mathur and Gurjar, 2002;Tomar and Chandel, 2006;Pandey and Prasad, 2007;Sitara et al, 2008;Mesta et al, 2009;Gupta and Bhadauria, 2012;Gupta et al, 2014).

The study is aimed at evaluating the antifungal potential of plant parts of Momordica charantia against the Fusarium oxysporum. During investigation ethanolic extracts of stem showed maximum inhibition in both, spore germination (at 50mg/mL) and mycelial growth (at 50% concentration) with 86.10±4.80 and 79.04±1.06 % inhibition respectively. This was followed by root (with 64.81±3.20 and 62.78±2.85%), leaves (64.28±0.00 and 59.55±0.99%), and fruit (50.97±3.40 and 43.99±1.85%). Aqueous extracts of all plant parts showed a comparatively less significant amount of inhibition in spore germination and mycelial growth. Aqueous extracts (at 50 mg/mL concentration) of root showed 48.88±3.85% inhibition in spore germination followed by fruit (39.39±5.24), leaves (37.03±3.20%) and stem (33.32±3.04%). Even at 50% concentration, aqueous extracts of leaves (14.86±1.00%), root (13.11±1.23%), stem (7.04±0.98%), and fruit (4.05±2.01%) was not found effective in inhibiting the mycelial growth of F. oxysporum. Ethanolic extracts of fruit showed 0.625 mg/mL MIC value against F. oxysporum while ethanolic extracts of the leaves and root exhibited 2.5 mg/mL and stems 1.25 mg/mL MIC for F. oxysporum. The plant parts of Momordica charantia were also found rich in phenolics, tannins, flavonoids and saponins. These compounds may be responsible for the antifungal activity of respective plant part.
