Growth and yield of cotton were best with combinations of fumigants and organophosphate and carbamate nematicides. Organophosphates or carbamates used alone did not give season-long control of root-knot nematodes. Long-term control was poor because the temporary sublethal effects of these materials diminished soon enough lhat the nematodes could reproduce. The nematodes survived the treatments ...

Stored-product insects infest raw grain, processed cereal grains, warehouses, and foodprocessing facilities such as flour and feed mills. The presence of insects in commodities or structures leads to quantitative and qualitative losses of grain and processed food. The presence of insects and insect-related materials (insect fragments) in processed products is regulated by federal food and drug ...

The use of the gaseous funaigant-nematicide methyl bromide in agriculture is scheduled to be phased out in the year 2001.1,3-Dichloropropene (1,3-D) in combination with chloropicrin and an herbicide is considered to be a viable alternative to methyl bromide for some crops. 1,3-Dichloropropene consists of two isomers, cis- and trans-l,3-D. A number of soil bacteria have been shown to initially d...

Archaeological bones are usually dated by radiocarbon measurement of extracted collagen. However, low collagen content, contamination from the burial environment, or museum conservation work, such as addition of glues, preservatives, and fumigants to "protect" archaeological materials, have previously led to inaccurate dates. These inaccuracies in turn frustrate the development of archaeologica...

Effective mole control is often difficult to achieve. Various types of traps, baits, and fumigants have been developed over the years to reduce mole damage to lawns, golf courses, and other areas. Two studies were conducted in the St. Louis, Missouri area to field test products currently registered by the EPA for mole control. Reliable census methods are required to determine efficacy. The best...

Agricultural productivity and sustainability are continually challenged by emerging and indigenous pathogens. Currently, many pathogens can be combatted only with biocides or environmentally dangerous fumigants. Here, we report a rapid and pathogen-specific strategy to reduce infection by organisms that target plant roots. Combinatorially selected defense peptides, previously shown to effect pr...

The Internet of Things (IoT) and convolutional neural networks (CNN) integration is a growing topic interest for researchers as technology that will contribute to transforming agriculture. IoT enable farmers decide act based on data collected from sensor nodes regarding field conditions not purely experience, thus minimizing the wastage supplies (seeds, water, pesticide, fumigants). On other ha...
