Thripenema fuscum n. sp., a parasite of the tobacco thrips, Frankliniella fusca, is described and illustrated from material collected from peanut (Arachis hypogaea) in Marianna, Florida. Thripenema fuscura can be distinguished from all other previously described Thripenema spp. by the dorsal curvature of the male and the presence of a stylet in the male. Highest parasitism rates of F. fusca by ...

The concept of a linear increase in harvest index, dHI/dt, has proven very useful for crop simulation modeling. The effect of high temperature on the response of dHI/dt of pods and seeds of peanut (Arachis hypogaea L.) has not been described. The objectives of this work were to determine (i) whether dHI/dt was linear at high temperature, (ii) whether high temperature affected dHI/dt and/or the ...

The object of this experiment was to determine the response of peanut when planting in single or twin row patterns by strip tillage or no tillage methods. During 1997 and 1998 the peanut cultivars "Georgia Green" and "Georgia Runner" or "Georgia Green" and "Georgia Bold" (Arachis hypogaea L.) were planted in 9.5 or 9.0 inch twin row patterns versus 36 inch single rows at the same seeding rate (...

Peanut (Arachis hypogaea L.) remains an important agronomic crop in Alabama, Florida, and Georgia. In recent years, the value of Alabama’s 190,000-acre peanut crop has exceeded $120 million annually. However, the diseases early leaf spot, late leaf spot, and southern stem rot may greatly reduce the profitability of Alabama’s peanut crop due to lower yields and poorer nut quality (7). Also, fung...

The commodity markets have been bidding for acreage due to bio-fuels creating new markets for corn and soybeans. This demand-driven market may continue to provide marketing opportunities for 2008-2010. Currently, the major decision facing producers is determining the enterprise mix for 2008. This memo compares the Returns over Variable Costs for corn and peanuts and analyzes the break-even yiel...

nematicide, D-D(1,2-dichloropropane1,3dichloropropene), resulted in the greatest flowering with the controls giving the lowest (Table 2). The less effective nematicide, ethoprop (O-ethyl S,S-dipropyl phosphorodithioate), had an intermediate effect on flowering. In these tests, flowering was positively correlated with yield and negatively related to soil nematode populations and root-gall indice...

Phytoextraction is a remediation technology that uses plants to remove heavy metals from soil. The success of a phytoextraction process depends on adequate plant yield (aerial parts) and high metal concentrations in plant shoots. A paper towel experiment was conducted to investigate the effects of plants sunflower (Helianthus annuus), maize (Zea maize), pearl millet ( Sorghum bicolour), green g...

The current study was aimed to explore the genetic diversity among seventy Pakistani accessions of Arachis hypogaea. In Pakistan their morphological and biochemical variations have already documented but still so far, molecular variations need to be studied for this valuable crop. For molecular diversity study DNA was extracted from all seventy accessions of Arachis hypogaea. The extracted DNA ...
