Toxic- Invasive Weed (Pic Credit- Phys.org)





According to a brand new research, the poisonous, invasive herb Ageratum conyzoides, also called billy goat weed, may be bio-converted into nutrient-rich compost for crop cultivation. The research, which was printed within the journal Biomass Conversion and Biorefinery in March, found that the compost was environmentally secure and perfect to be used as a soil conditioner to enhance farmlands.












Findings of Study:

According to Krishna Chaitanya Maturi, an creator of the research and researcher on the Indian Institute of Technology (IIT) Guwahati, the detrimental influence of A. conyzoides weeds is nicely documented, significantly in degrading soil high quality by decreasing helpful soil organisms. The invasive weed, also called billy goat weed and chickweed, is native to South America.

“As a result of the presence of toxic allelochemicals such as stigmasterol, demethoxy-ageratochromene, and caryophyllene in A. conyzoides, it is harmful to neighbouring crops.” “It also disrupts various aboriginal plant cultures in various ecological regions,” Maturi explains to SciDev.Net.

According to Ajay S. Kalamdhad, co-author and professor of Environmental Engineering at IIT, the research’s purpose was to create a non-toxic product by biologically treating the plant and mixing it with inoculums (a mix of microorganisms and natural matter) and bulking brokers in a rotary drum composter.

“The composter was capable of increasing nutritional parameters like nitrogen, phosphorus, and potassium while decreasing lignin, hemicelluloses, and cellulose,” Kalamdhad says. “The use of A. conyzoides for in-vessel composting is a novel approach to obtaining a value-added product that is rarely reported in other management technologies.”












Kalamdhad claims that statistical evaluation revealed an in depth relationship between biodegradation and dietary merchandise after composting. “As a result, the study suggests that A. conyzoides compost can be used in a variety of farming applications that require a nutrient-rich, non-toxic, environmentally acceptable product,” he continued.

According to an FAO paper, the worth of A. conyzoides in growing soil fertility is a part of indigenous information amongst farmers in Arunachal Pradesh’s mid-hills. According to the paper, farmers in Arunachal Pradesh consider the plant can be utilized to extend rice grain yields by bettering soil chemical properties and fertility.

Okay.C. Jisha, an assistant professor at Kerala’s Muslim Education Society College who was not concerned within the research, believes the findings might be helpful to agro-industry policymakers searching for efficient weed administration methods. “A. conyzoides compost can be used as a replacement for chemical fertilizers,” she tells SciDev.Net.

“Plants within the [Asteraceae] household are wealthy in bioactive compounds like polyphenols, terpenoids, and flavonoids, and their important oils have lengthy been used [in traditional medicines such as for skin diseases and diarrhoea,” says R. Seema Devi, a researcher specializing in the phytochemistry of aromatic medicinal herbs and assistant professor at the N.S.S. College, Manjeri, Kerala.












“A. conyzoides is an annual herb used to treat skin diseases, diarrhoea, and gynaecological issues in folk and ethnobotanical medicine. It has anti-microbial, anti-inflammatory, anti-malarial, and other properties, according to research.”
