“…Phytotoxicity damage had been studied by seedling and detached leaf bioassays. Results indicate, Tween 80 at 0.5% to be the best formulant, while the combination of Tween 80 and coconut oil at 0.5% was found to exhibit maximum damage to Parthenium seedlings and detached leaves (Quereshi et al, 2010). Thus in our present research work, results were in accordance to results obtained earlier wherein, Tween 80 has been reported to be most compatible formulant (Kalam et al, 2014).…”

“…Loss of turgidity, drying finally culminated into seedling collapse. Similar results have been reported by Quereshi et al, 2010). Detached leaf bioassay results depict toxicity which initiated with slight necrosis and at advanced stage after 48 hpt acute necrosis was observed with wilting of entire leaves leading to complete death of foliar tissue Formulation is a process of mixing the secondary metabolite or the microbe with some inert carriers to alter their physico-chemical characteristics to enhance the shelf life and field performance of resulting formulated product.…”

Biological control is the only cost-effective, environmentally benign and ecologically viable method available for the control of deadly weeds. Lantana camara is a global weed, which imposes deleterious economic effects on humans and livestock. Microbial products tend to offer a non-chemical alternative in controlling noxious, invasive and pernicious weeds like Lantana. Microbial secondary metabolites or agribiologicals are biotechnological products, which have provided new incentives for natural herbicidal products research. They are environmentally and toxicologically benign in comparison to traditional chemical herbicides. Phoma is a well-known phytopathogenic fungus known to produce an array of bioactive extracellular toxic compounds. Present work deals with screening various agrowastes for phytotoxin production at economically feasible rates followed by formulating them to facilitate their absorption and translocation within host foliar tissues. Herbicidal potential of test strain, was evaluated by shoot cut, seedling and detached leaf bioassays. Standardization and optimization of parameters for production of agribiologicals was achieved from Phoma sp. FGCC#48. Arhar bran extract proved to be the best agrowaste, producing maximum phytotoxin, with tween 80 as a formulant @ 0.5% and this combination could be developed as a potential herbicide against the pernicious weed Lantana.

“…Such metabolites represent a large pool of compounds that can enhance crop growth and crop protection (Izurdiaga et al 2023). Quereshi and Pandey (2007) extracted the cell-free culture extract of Phoma sp. FGCCW#54 which exhibited excellent herbicidal properties against Parthenium hysterophorus.…”

Weeds are the main competitors to the crop for various resources like nutrients, moisture, light, space, etc. They are one among the biotic factors which cause severe yield reduction (45%), increase the cultivation cost and decrease the input effi-ciency when compared to other biotic factors like insects (30%), diseases (20%) and other pests (5%). An economic loss of around 11 billion USD has been estimated due to the infestation of weeds in 10 major crops of the Indian sub-continent (Gharde

Phoma macrostoma Montagne 94-44B is an effective bioherbicide for broadleaved weed reduction. In 2016, Health Canada's Pest Management Regulatory Agency (PMRA), under the authority of the Pest Control Products Act and Regulations, granted full registration for the sale and use of the bioherbicide P. macrostoma Montagne 94-44B to control a broad spectrum of broadleaf weeds in established turfgrass and new seeding of grasses as well as in field grown nursery plants, trees and container-grown ornamentals. P. macrostoma 94-44B colonizes susceptible and non-susceptible plant roots, however, only in susceptible plants, such as Taraxacum officinale (dandelion), do mycelium proliferate around the vascular trachea interfering with the function of neighbouring cells while not entering them. Macrocidins, secondary metabolites secreted by P. macrostoma 94-44B mycelia, inhibit multiple steps in carotenoid precursor formation including phytoene desaturase and steps associated with β carotene and lutein carotenoid biogenesis, Fe and Mg chelation and OJIP chlorophyll fluorescence, thus uncoupling the light-harvesting complex of photosystem II from the reaction centre. The combined actions of P. macrostoma 94-44B and macrocidins elicit photobleaching of the leaves and eventual weed death. Research is underway to exploit Phoma's bioherbicidal actions for weed management in agriculture. P. macrostoma 94-44B can be used to reduce broadleaved weeds in crops such as wheat, corn, potato, forage grasses and established alfalfa (2nd growth or older). Soil residue studies reveal that neither P. macrostoma 94-44B nor macrocidins are present after 1 year suggesting that farmers could plant Phoma-sensitive crops such as legumes, flax or canola in subsequent years.
