The importance of soil health
Though it is the foundation of life, soil constitutes only a thin layer of material on the surface of our planet. It provides the necessary weathered minerals, organic materials, air, and water, which are the most precious resources for all living creatures. Plants find life in soil, as it provides a rooting medium and nutrient source for plants to grow. Through healthy plants, ...

Methyl bromide as a fumigant for International transports
Methyl bromide is a is an odourless, colourlessgas most often used as a fumigant. About 70% of methylbromide produced in the United States goes into pesticidal formulations. 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 ...

Tips for Using Beneficial Nematodes in the Summer
Now that summer is underway and temperatures are steadily rising, we are getting a lot of questions about how to effectively order, store and apply beneficial nematodes in the heat. Beneficial nematodes are a great, natural and effective option for controlling a wide variety of pest insects this time of year. The ideal time to apply nematodes can depend on the type of pest(s) you are targeting. ...

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, ...

Integrating ecosystem services into crop protection and pest management: Case study with the soil fumigant 1,3‐dichloropropene and its use in tomato production in Italy
Ecosystems provide the conditions for producing food, regulating water, and providing wildlife habitats; these, among others, are known as ecosystem services (ESs). Food production is both economically and culturally important to southern European farmers, particularly in Italy where farmers grow flavorsome tomatoes with passion and pride. Growers rely on pesticides for crop protection, the ...

Plant Sciences in Agriculture
Plant pathogens Microorganisms, also called as microbes, live in every part of the biosphere, including soil, water, and air. Plant pathogens are the microbes that infect plants and cause diseases. In history, some plant diseases led to tremendous negative impacts on society. In 1845, potato blight disease was prevalent in all potato growing regions in Ireland. Phytophthora infestans, a fungus, ...

Compatibility of Soil-Dwelling Predators and Microbial Agents and their Efficacy in Controlling Soil-Dwelling Stages of Western Flower Thrips Frankliniella Occidentalis
Western flower thrips (WFT) generally pupate in the soil. This laboratory study was designed to examine the compatibility of soil-dwelling predators with microbial biocontrol agents and assess their combined efficacy against pupating WFT, with a view to their integrated use. The following commercially available biocontrol agents were evaluated: a rove beetle, Dalotia coriaria (Kraatz); predatory ...

Toxicity in relation to mode of action for the nematode Caenorhabditis elegans: Acute‐to‐chronic ratios and quantitative structure‐activity relationships
Acute‐to‐chronic ratios (ACRs) and quantitative structure‐activity relationships (QSARs) generate continuous interest in particular in chemical risk assessment. Previous studies focusing on the relationship between the size or variation of ACRs to substance classes and QSAR‐models were often based on data for standard test organisms, such as daphnids and fish. For the present study, we ...

Banana leaf and glucose mineralization and soil organic matter in microhabitats of banana plantations under long‐term pesticide use
Soil organic matter (SOM) and microbial activity are key components of soil quality and sustainability. In tropical humid tropics of Costa Rica three pesticide regimes were studied: fungicide (low input); fungicide and herbicide (medium input); and fungicide, herbicide and nematicide (high input), under continuous banana cultivation for 5 (young) or 20 (old) years, in three microhabitats: ...

Three soybean plant introductions possess unique resistance to peanut root-knot nematode
Peanut root-knot nematode [Meloidogyne arenaria (Neal) Chitwood or Ma] is an increasingly common pest in the southern United States where crops such as peanut (Arachis hypogaea L.) and soybean [Glycine max (L.) Merr.] are grown. Four soybean plant introductions (PIs) are highly resistant to the peanut root-knot nematode. To determine if PI 594403, PI 594427C, and PI 594651B contain useful ...

Root-lesion Nematodes reduce yield of intolerant wheat and barley
Root-lesion nematodes (Pratylenchus neglectus and P. thornei) are widely distributed and substantially reduce grain yields in wheat (Triticum aestivum L.)-producing regions of the Pacific Northwest (PNW). The objective of this research was to determine if wheat and barley (Hordeum vulgare L.) cultivars differ in tolerance to these nematode species. Field experiments were conducted by comparing ...

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; ...

Linkage mapping of resistance to reniform nematode in cotton following introgression from gossypium longicalyx (Hutch. & Lee)
Reniform nematodes (Rotylenchulus reniformis Linford & Oliveira) decrease U.S. production of Upland cotton (Gossypium hirsutum L., 2n = 52, 2[AD]1) by more than US$100 million yr–1. We report here on the mapping of a gene for extreme resistance that was introgressed from the African species G. longicalyx (Hutch. & Lee, 2n = 2x = 26; 2F1). The responsible allele, designated Renlon, was localized ...

Tests of taxonomic and biogeographic predictivity: Resistance to disease and insect pests in wild relatives of cultivated potato
A major justification for taxonomic and biogeographic research is its assumed ability to predict the presence of traits in a group for which the trait has been observed in only a representative subset of the group. Such predictors are regularly used by breeders interested in choosing potential sources of disease and pest resistant germplasm for cultivar improvement, by genebank managers to ...

Root-knot nematode-resistant alfalfa suppresses subsequent crop damage from the nutsedge-nematode pest complex
Southern root-knot nematode [RKN, Meloidogyne incognita (Kofoid & White) Chitwood], yellow nutsedge (YNS, Cyperus esculentus L.), and purple nutsedge (PNS, C. rotundus L.) occur together as a mutually beneficial pest complex in sandy soils. All crops grown in infested soils are affected due to the wide host range of the nematode, the perennial life cycle of the nutsedges, their interactions, ...
