CHEMICAL PROTECTION OF SOYBEAN CROPS AGAINST WEEDS

2021
One of the most pressing problems in the development of domestic agriculture is the significant weeding of crops, including soybeans. Soil and climatic conditions of Ukraine mainly contribute to the cultivation of this crop. At the beginning of the growing season, soybeans grow relatively slowly, and weeds compete with them for moisture, nutrients ...

Chemically mediated multitrophic interactions and their role in crop protection

Current Opinion in Insect Science
Agricultural production is primarily constrained by biotic stresses, with insect pests being the most significant contributors. Effective pest management is essential for sustainable crop protection and relies on understanding how plants interact with pests (herbivores), their natural enemies (predators and parasitoids), other plants, and beneficial ...

Microencapsulation of a Crop Protection Compound by Initiated Chemical Vapor Deposition

Macromolecular Rapid Communications, 2012
AbstractIn this work, initiated chemical vapor deposition (iCVD) has been employed as a one‐step liquid‐free process combining polymerization and coating for the encapsulation of 3D non‐planar substrates. Coatings have been applied using iCVD specifically to encapsulate microparticles of a highly water‐soluble crop protection compound (CPC) for ...

Chemical crop protection research. Methods and challenges

Pure and Applied Chemistry, 2002
Abstract Chemical crop protection, today a well-established technology to support sustainable production of food, feed, and fiber, will continue to play an important role in agribusiness in spite of the emergence of novel biotechnological solutions.

Chemical crop protection research and development in Europe

1997
Abstract The following five theses are discussed: 1. The majority of the crop protection research and development money is spent by European companies. These efforts are targeted at a global market. The relative importance of the European market strongly varies with the crops and the different pests. 2. Crop protection research and development is a

Crop protection by chemical means

1998
KEMIJSKA ZAŠTITA BILJA- Štete od nametnika na poljoprivrednim kulturama, su velike. Noviji podaci ukazuju da stetočinje smanjuju urode poljoprivrednih kultura u svijetu za 42 %, a u Europi 23 % (Oerke 1993) Promatrano kroz duže razdoblje štete od nametnika u Hrvatskoj na poljoprivrednim kulturama iznose 29.2% što u novčanim pokazateljima iznosi oko ...

Crop protection: the role of the chemical industry in an uncertain future

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1981
Abstract Chemical means for the control of weeds, pests and diseases have become legion during the last 40 years, to the point at which it might superficially appear that all the major problems are solved. An international industry earning more than £4000M has grown up, and spends around £250M annually on research and development: in ...

Integrating use of beneficial organisms with chemical crop protection

Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1988
Abstract The selectivity of insecticides, particularly of pyrethroids, is described and possibilities are proposed for further development of selectivity. The production of beneficial organisms resistant to pesticides by techniques including genetic manipulation is discussed. Preliminary studies on the use of semiochemicals to improve
