Abstract

Organic farming prohibits use of synthetic agrochemicals and encourages use of Integrated Pest Management (IPM) methods. States in the Southeastern US generally lag behind the rest of the country in organic vegetable production partly because of high insect pressures that make it difficult to grow vegetables without pesticides. This study on summer squash (Cucurbita pepo), grown using organic management practices, was conducted at a research station located in Mills River, North Carolina. The objectives of the study were to assess insect population dynamics and to evaluate performance of three OMRI-approved bio-pesticides: Azadirachtin, Pyrethrin and Spinosad against major …

Abstract

Probiotics are beneficial to gastrointestinal health and have anti-inflammatory properties. An experiment was conducted to determine if L. reuteri could protect mice from azoxymethane-induced colorectal cancer (AOM-CRC). A/J mice were randomly assigned to controls, pre-treatment, or post-treatment groups. The mice in the groups were injected with 10mg/kg body weight of AOM and treated with L. reuteri; given only AOM; given only L. reuteri; or given neither AOM nor L. reuteri. At the end of a 26-week latency period, the mice were euthanized, dissected, and colons examined for tumors. L. reuteri did not protect animals against tumor …

Abstract

Kaolin geophagia is associated with the relief of gastrointestinal distress, but it may also cause adverse health effects on the body. This study was designed to: assess kaolin composition; test if 129SvEv mice would consume kaolin and determine the consequences of consumption; and assess rotational stress modulation of consumption. Thirteen kaolin samples were purchased from Alabama and Georgia stores. Chemical and physical properties were characterized for each sample using a Munsell chart, pH meter, Energy Dispersive Spectroscopy, Transmission Electron Microscopy, Visible Near-InfraRed Spectra, and Inductively Coupled Plasma-Optical Emission Spectrometry. Kaolin was then given to mice as food supplements and …

Overview Of The Integrated Pest Management (Ipm) Terrain And Activities In Furtherance Of The Walmart Initiative To Purchase Fresh Vegetables From Local Growers In Alabama, Franklin Quarcoo, Conrad Bonsi

Professional Agricultural Workers Journal

Tuskegee University has been providing various types of technical expertise to limited resource farmers who have been supplying Walmart with collard greens, watermelons and purple hull peas. A number of pests bedevil the cultivation of these crops; cost-effective management methods for these pests are needed. The objectives of this paper are to document the IPM activities associated with supplying produce to Walmart; summarize pest problems encountered on the afore-stated crops; recommend IPM methods suitable for limited resource farmers; and suggest other activities that ensure that farmers incur even less pest-related crop losses. Anthracnose was the major pest encountered on watermelons. …
