Parthenium Weed

Parthenium hysterophorus Linn. is one of the most aggressive, invasive weeds threatening natural and agricultural ecosystems in Nepal. Leaf feeding beetle, Zygogramma bicolorata Pallister (Coleoptera: Chrysomelidae), is regarded as a potential candidate for biological control of Parthenium weed. Considering the fact effectiveness of Z. bicolorata against P. hysterophorus was evaluted in Nepal. Z. bicolorata caused 98.25 % defoliation of P. hysterophorus reducing 38.88 % plant height, 27.29 % plant width, 26.25 % root length, 12.33 % leaves, 40.58 % shoot biomass and 36.59 % root biomass in the period of 90 days. The flower production and soil seed bank were reduced by 50.22 % and 40.29 %, respectively. Z. bicolorata was an efficient bio-control agent with a significant negative effect on the vegetative and reproductive performance of the noxious weed P. hysterophorus.

Parthenium hysterophorus, often known as congers grass, is a noxious weed that is a member of the Asteraceae family of plants. Its natural habitats include the areas surrounding the Gulf of Mexico, Central America, Southern North America, the West Indies, and Central South America, among other places. Congress grass has risen to become one of the world’s seven most destructive and deadly weeds, according to the World Health Organization. This invasive plant is also a significant concern in India. It is responsible for a variety of illnesses and allergies in both people and animals. Aside from that, there is some potential for this plant to be used as an insecticide, herbicide, fungicide, wood preservative, anti-amoebic, and even for medicinal purposes. If any species, particularly an invasive weed, is to be evaluated for its ability to benefit living organisms, it is necessary to have a thorough understanding of both its positive and negative impacts. As a result, this review paper is an attempt to describe the present state of knowledge regarding the hazardous and helpful effects of Parthenium hysterophorus on people and animals.

First Record of EntomopathogenBeauveria Bassiana(Bals.-Criv.) Vuill. OnZygogramma BicolorataPallister, A Biocontrol Agent ofParthenium HysterophorusL.Entomopathogenic fungi have great potential as biological control agents against insect pests. So they are being developed worldwide for the control of many pests of agricultural importance. But their effect on non-target insects, such as natural enemies has been a matter of great concern. Recently we came across an entomopathogen infecting a laboratory culture ofZygogramma bicolorata, a potential biocontol agent of noxious weed,Parthenium hysterophorus. The pathogen was isolated from the grubs and beetles and identified asBeauveria bassiana. In the present paper, the entomopathogen,B. bassianais reported and described for the first time from the laboratory culture ofZ. bicolorata.

Physical And Chemical

To explore the mechanism for saving energy and reducing consumption in pelletizing process, the pelletizing process is decomposed correlatively into two parts: the material flow process and energy flow process. On this basis, it is studied that the physical and chemical changes and the flow mechanism in ferrite flow and carbon flow respectively, by analyzing the changes and conversion of the ferrite and carbon flow in pelletizing process, variation of material and energy flow has been summarized, using the law to guide the production, minimizing consumption of energy and maximizing resource utilization will be achieved. It provides another path to reduce energy consumption for steel plant.
