Spring is coming…How Early Can You Apply Nematodes?
Spring is on its way, and many of us are looking forward to more time spent outside. A common question we get this time of year is “when can I apply beneficial nematodes”? Beneficial nematodes are a great, all-natural control for a variety of common pest insects. But, since nematodes are living organisms, care needs to be taken to ensure they stay living and viable. As a general rule, ...

It has been used to fumigate agricultural commodities, grain elevators, mills, ships, clothes, furniture greenhouses and delicate works of art. Non-pesticidal uses include degreasing wool and extracting oils from nuts, seeds ...

Crop response to rotation and tillage in peanut-based cropping systems
Production of peanut (Arachis hypogaea L.) in reduced tillage systems has increased in the United States during the past decade. However, interactions of tillage system and crop rotation have not been thoroughly investigated for large-seeded, Virginia market type peanut. Research was conducted at two locations in North Carolina during 1999 to 2006 to compare yield of corn (Zea mays L.), cotton ...

Soybean yield and soybean cyst nematode densities related to soil ph, soil carbonate concentrations, and alkalinity stress index
Soybean [Glycine max (L.) Merr.] grown on high pH, calcareous soils often suffer yield loss due to unavailability of Fe. Further yield decline can occur due to infestations by soybean cyst nematodes (Heterodera glycines Ichinohe; SCN) that are often present in greater numbers in high-pH soils. An observational study was conducted from 2001 to 2005 in Iowa to examine the relationships among: pH; ...

Detecting plant root diseases & pests
Soil-borne pests and diseases are harder to detect than those on the aerial parts of a plant. Visible symptoms in leaves and stem appear only in the final stages of the attacks. If plants are treated at this point, it may be difficult to avoid plant injury, as plants could already have been severely impacted. Early detection and identification are key to prevent crop loss. There are, however, ...
