4-Sulfenyl-2-carbamoyl-4-isoxazolin-3-ones (4) were designed on the basis of biological isosterism and prepared in four steps. Some of these compounds showed sufficient pre-emergent herbicidal activities against various kinds of weeds. Among the synthesized compounds, 2-(N-(4-chlorophenyl)-N-isopropylcarbamoyl)-4-ethylthio-5-methyl-4 -isoxazolin-3-one (4cd) exhibited the most promising activity.

The Hindu Vedas place teachers on a high pedestal: “a guru creates and sustains knowledge, and destroys the weeds of ignorance, just like the creator, the sustainer, and the destroyer of this universe”. It is no surprise then that students see teachers as authority figures that teach them the truth. Thus, the teacher has a profound responsibility to guide students by helping them to assimilate ...

BACKGROUND: Application of plant mulches plays a significant role in development and expansion of sustainable farming systems. OBJECTIVES: Assessment effect of chemical and non-chemical weeds management methods on weeds density and biomass and the properties of soil, including microbial biomass carbon (MBC) and soil organic carbon (SOC) in potato cultivation. ...

Farming is cultivating the soil, producing crops, and keeping livestock. The agricultural sector plays a crucial role in country’s economic growth. This research proposes two-stage machine learning framework for agriculture to improve efficiency increase crop yield. In first stage, algorithms generate data extensive far-flung areas forecast crops. recommended crops are based on various factors ...

Plant health is essential for food security, and constitutes a major predictor to safe sustainable systems. Over 40% of the global crops' productions are lost pests, insects, diseases, weeds, while routinely used chemical-based pesticides manage menace also have detrimental effects on microbial communities ecosystem functioning. The rhizosphere serves as seed bank where microorganisms transform...

Experts diagnose plant diseases and insect pests via long-distance video is a new and effective way for prevention and cure. Jabber based on XMPP. So there are good communication, standardization and expansibility in Jabber. This thesis gave a method which was long-distance video diagnosis based on Jabber. First, VFW was used to capture video of diseases and insect pests. Second, H.264 compress...

A major challenge in berry production is the management of pests. Traditionally, growers have used pesticides to manage weeds, arthropods and pathogens, but pressure has been increasing to reduce or eliminate their use. A multitude of approaches and technologies exist that could potentially reduce pesticide use and increase consumer acceptance of berries. Many of these have not yet been widely ...
