Anthracnose leaf disease in rubber trees, caused by the attack of Colletotrichum gloeosporioides, have led to the serious decline in natural rubber production. Continuous usage of synthetic fungicide leave the toxic residues that harm the surrounding animals and plants and are not environmentally friendly. It needs a better solution with organic products that are safer, more effective and biodegradable. Piper species could be considered as a source of new natural products with potential antifungal activities.

Colletotrichum gloeosporioides Penz. and Sacc. is associated with aonla anthracnose, and fungicides remain one of the important means to manage the disease. In-vitro evaluation of the fungicides revealed that all the treatments significantly inhibited mycelial growth of the test pathogen over untreated control.

Colletotrichum gloeosporioides Penz. and Sacc. is associated with aonla fruit rot. Laboratory studies were conducted to study the effect of different solid media on mycelia growth and sporulation of Colletotrichum gloeosporioides Penz. and Sacc. Among all the solid media tested, maximum mycelial growth with excellent sporulation rating was obtained on Richard’s agar medium (90 mm) within six days and was significantly superior to all the other media tested.

Colletotrichum gloeosporioides Penz. and Sacc. is associated with aonla, in that fruit rot of aonla is one of the contributing factors for this low productivity. Therefore, the ecofriendly and environmentally safe management of fruit rot disease with the use of plant extracts is necessary. Different plant extracts evaluated under in vitro condition against the mycelial growth of Colletotrichum gloeosporioide. Plant extracts viz., Allium sativum (82.74 %), Azadirachta indica (80.77 %), Ocimum sanctum (77.1 %) mycelial growth inhibition of fungus under laboratory dual culture technique.

Colletotrichum gloeosporioides Penz. and Sacc. is associated with aonla, in that fruit rot of aonla is one of the contributing factors for this low productivity. Therefore, the ecofriendly and environmentally safe management of fruit rot disease with the use of bioagents is necessary. Different bioagents and plant extracts evaluated under in vitro condition against the mycelial growth of Colletotrichum gloeosporioide revealed that fungal bio agents viz., Trichoderma viride (85.03 %) T. harzianum (82.56 %) and Trichodermah hamatum (81.08 %) mycelial growth inhibition of C.

The present study was conducted to evaluate the efficacy of aqueous extract and dry extracts of 12 different plant species against C. gloeosporioides the causal agent of mango anthracnose under natural disease epidemics. Significant difference was observed among the extracts in their effect on suppressing the mycelial growth of the pathogen under in vitro conditions. None of the extracts were able to completely prevent the development of the pathogen. However, most of the extracts significantly reduced disease development over the control. Among the fresh plant extracts, at 7.

Bananas, chilies and oranges are the most widely grown plants in Viet Nam. However, their fruits are severely affected by anthracnose disease caused by Colletotrichum gloeosporioides. Therefore, the objective of this study was to evaluate the effects of CaCl2 on invitro mycelial growth and in vivo lesion diameters on pisang awak bananas, oranges and chillies .
