Abstract

One of the most significant biotic constraints that wheat production faces is weed infestation. Wheat is infested with different weeds that cause yield losses (up to 100%) that vary based on the type of weed, their density, and the environmental conditions. Chemical weed control is the most common method to control weeds in wheat. However, widespread herbicide resistance (>365 cases worldwide) has challenged the sustainability of this method. Use of nanoherbicides is a promising strategy to cope with the issue of herbicide resistance. To achieve weed control conditions during the whole growing season, nanoformulations of herbicides are a delivery strategy that involves covering an active component with various materials that vary in size from nano to nanoscale and then releasing the substance in a controlled manner. Nanoherbicides prevent leaching and volatilization of active components and premature degradation through photolysis, hydrolysis, and biodegradation. According to studies, nanoencapsulation of herbicides produces more targeted and less hazardous agricultural formulations. Using nanoherbicides in lower concentrations is beneficial. It lessens the long-term impacts of herbicide residues in wheat fields and the toxicity of these herbicides to the environment. It is also beneficial in eliminating the weeds without ever interacting with the crop plants, which eventually results in a greater wheat yield. This review provides a comprehensive overview of the emerging field of utilizing nanoparticles (NPs) in herbicides for effective weed management in wheat crops. This article explores the novel approach of integrating NPs with herbicidal agents, highlighting their potential benefits and challenges. The review also addresses the current state of research, recent advancements, and potential future directions in this evolving area of agricultural science.

49. Evaluating University Teacher's Perception about E-Teaching during Pandemic in the Higher Educational Institutes of Pakistan

Author

Nadeem, Muhammad Asif, Nisa, Zaib u., and Shah, Manzoor Husain

Abstract

The objective of the research was to identify teacher's readiness towards the acceptance of technology assessment model in e-teaching and identification of the problems faced by the teachers while switching to e-teaching. The nature of the study was qualitative. Data was collected from 04 public sector universities. Purposive sampling technique was used to select the group of the study. Sample consisted of the teachers (male and female) teaching in the teacher training institutes of southern Punjab (Pakistan). 20 teachers from various universities were selected for the interview. Research tool used for the data collection of the study was structure interview. The interview for the teachers consisted of eight questions. The results of the study stated that the teachers faced problem while e-teaching during pandemic related to a number of factors such as social influence, perceived ease of use and perceived usefulness. The teachers may work to integrate e-teaching with conventional learning and be proficient in web-based education platforms.
