Mango malformation (MM) is an ambiguous mango disease with tremendous economic importance throughout the mango growing regions. Several studies reported that Fusarium species especially Fusarium mangiferae is associated with mango malformation. Silicon is an essential element, which plays a vital role in plant microbial interaction. It deposits under the cuticle and acts as a physical barrier that protects the plant from fungal infection.

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.

In-vitro compatibility studies of B. bassiana (Bb-5a) with ten insecticides were examined on PDA media by poisoned food technique to develop suitable combinations for the control of whitefly in sunflower ecosystem. Out of ten insecticides, nine insecticides viz., imidacloprid, thiamethoxam, acetamiprid, clothianidin, acephate, fipronil, buprofezin, flonicamid and azadirachtin showed compatible with B. bassiana at recommended dose (RD), half of the recommended dose (0.5 × RD) and double the recommended dose (2 × RD) at 14th and 30th DAI.

Six fungicides viz., captan 50 WP, copper oxychloride 50 WP, dodine 65 WP, mancozeb75 WP, propineb70 WP and zineb 80 WP were evaluated against rice sheath blight (Thanatephorus cucumeris). The in-vitro evaluation of these fungicides through poisoned food technique at five different concentrations viz., 50, 100, 200, 500 and 1000 µg a.i ml-1 indicated that mancozeb proved the most effective exhibiting mean mycelial growth inhibition of 95.26 per cent followed by captan and dodine with 93.80 and 93.66 per cent, respectively. Copper oxychloride proved least effective and resulted in only 44.

The results of the study revealed thaturea was most effective in inhibiting the fungal growth at all the tested concentration. It was also found that soluble NPK and Potassium nitrate promoted the fungal growth at all the concentration. Among biorationals, bromonitropropanol gave the highest mycelial inhibition (73.72%), while sodium and potassium bicarbonates at lower concentration promoted the fungal growth, but inhibited the growth at higher concentration.
