“…Mulberry and Indian rose wood were infected by the genus Phyllactinia which was also reported by [15] and [12], respectively. Powdery mildew pathogens infecting butternut squash, asthma plant, bitter gourd, bottle gourd, sesame and common cockle bur were infected with Podospheara genera which are in agreement with the findings of several workers [9,16,8,17,18,13].…”

Powdery mildews are obligate biotrophic fungal pathogens that are responsible for disease on a wide range of host plants with white powdery patches on plant parts. An exhaustive survey in the Navsari region of south Gujarat was carried out to identify white powdery/floury circular to irregular spots, specks or patches either on the upper surface or lower surface or both the surface of the leaves. These powdery mildew symptoms were observed on leaves, stems and pods/fruits on 39 hosts of 22 families. For precise identification of the pathogen the morphological characteristics included mycelium, length and breadth of conidia, conidiophores, appressorium, conidial germ tubes foot cell and fibrosin bodies. Majorly the genera like Erysiphe, Golovinomyces, Leveillula, Oidium, Phyllactinia, Podosphaera, Micro-oidium and Sphaerotheca were found on different hosts in this region. The maximum number of hosts were infected by the genus Oidium followed by Erysiphe. The highest percent disease incidence was observed on the asthma plant, black gram, green gram and wild poinsettia between 75-100 per cent out of all the hosts.

The main principle of pest control in organic farming is to reduce the use of synthetic chemicals, especially pesticides. On the other hand, pest control in agricultural systems prioritizes the conservation of natural enemies in these ecosystems. Coccinellidae predators are one of the potential natural enemies available in organic farming ecosystems. To optimize the potential of these natural enemies, it is necessary to study the diversity of these predators in organic farming. By knowing the species and abundance of Coccinellidae predators in organic farming ecosystems, a suitable conservation model can be designed for these natural enemies so that these predators can carry out their functions to control pests, especially aphids. This study aims to study the diversity of predatory Coccinellidae in organic and inorganic agriculture in West Sumatra Province. Coccinellidae predators are collected directly and use insect nets. The diversity of Coccinellidae predators was analyzed with the Shannon Winner and Simpson abundance indexes. Based on the exploration carried out on several organic farms in West Sumatra, 18 species of Coccinellidae Predators have been collected, and six species have not been identified. Next, it is proven that organic farming has a high diversity of 1.90 compared to inorganic farming, which is 1.65. The presence of predatory Coccinellidae in organic farming is more evenly distributed, namely 0.67. Menochilus sexmaculatus is one species that has the potential to be optimized as a biological control agent for aphids.

Cucurbitaceae is the vegetable family enriched with numerous vitamins and minerals. In early rainy season cucurbits are the host of different fungal pathogens. In present study, four fungal diseases dominant on three members of cucurbitaceae family are observed in Bhoranj block of District Hamirpur, lie in lower foot hills of Himachal Pradesh. Four fungal diseases along with host plants are leaf spot of Lagenaria siceraria, downy mildews of Cucumis sativus, powdery mildews of Coccinia grandis and powdery mildews of Cucumis sativus. Among all these diseases, Disease Incidence and Disease Severity of Powdery mildews of Coccinia grandis are most dominant i.e. 40.3±1 and 51.2±1 respectively. Disease Incidence and Disease Severity of Leaf spot of Lagenaria siceraria is least i.e. 12.5±1 and 1.1±1, respectively.
