The impact of naturally occurring arbuscular mycorrhizal fungi on soybean growth and their interaction with Heterodera glycines were evaluated in nematode-infested and uninfested fields in Kansas. Ten soybean cultivars from Maturity Groups III-V with differential susceptibility to H. glycines were treated with the fungicide benomyl to suppress colonization by naturally occurring mycorrhizal fun...

Nitrogen (N) and fungicide are among the most important factors impacting wheat yields in Kansas. However, there is limited information on whether foliar fungicides interact with N rates yield determination. Thus, our objectives were to evaluate as impacted by different or without use of fungicide. One field experiment was established using a factorial structure five (0, 30, 60, 90, 120 pounds ...

in order to evaluate the effect of foliar application of micro nutrients on physiological growth indices and total dry matter yield of forage corn. field experiment was conducted in 2006 at bersian village isfahan. a randomized complete block design with four replications was used. plant treated with 8 foliar application treatments (fe, zn, cu, mn, fe + mn, cu + zn, fe + mn + cu + zn and contro...

Borage is an important medicinal plant which must be cultivated commercially in order to meet the ever-increasing demand for pharmaceutical industry. This study was done under hydroponics condition. Seeds of Borage were obtained from Neka Research Center (North of Iran). After applying Benomyl fungicide, the seeds were rinsed with distilled water and planted in vermiculite. After germination an...

the presented study aimed at investigating the effect of foliar application of amino acids and nano particles and chelated iron on photosynthetic pigments and yield of potato. to this end a factorial experiment was carried out in the form of randomized complete block design with three replications in 2013, in the research field of natural resources institute in damavand, iran. the first factor ...

To combat an increasing abundance of sucking insect pests, >40 pesticides are currently recommended and frequently used as foliar sprays on row crops, especially cotton. Foraging honey bees may be killed when they are directly exposed to foliar sprays, or they may take contaminated pollen back to hives that maybe toxic to other adult bees and larvae. To assess acute toxicity against the honey b...

Bird depredation of agricultural crops is a worldwide problem. New strategies to include chemical repellents are needed to mitigate crop losses. We evaluated 3 preplant seed treatments (Apron XLt LS [Syngenta Crop Protection, Greensboro, NC], Dividend Extremet [Syngenta], and Maximt 4 FS [Syngenta]), one foliar insecticide (Karatet with Zeon Technologye [Syngenta]), and one foliar fungicide (Ti...

An wspore germination technique was used to study the effectiveness of 27 fungicides, including some systemic ones, in inhibiting germination at various stages. Among the chemicals tested, Mersil, PMA10, and Panogen, each at a concentration of 500 ppm active ingredient, inhibited germination about 75%. Of the nonmercurial compounds, mancozeb and ethazole were the best giving about 60% inhibitio...

Registered treatments for the control of avocado anthracnose caused by Colletotrichum goeosporioides are post-harvest applications of prochloraz and thiabendazole. Pre-harvest treatments to reduce inoculum levels in the field are also an important factor for successful anthracnose disease control. Pre-harvest application of benomyl was previously registered for this purpose, although at this st...
