“…Biological insecticides are used against these aphids instead of using and Myzus persicae on sweet pepper were reduced at the highest concentration of neem extract. Neem extracts show high mortality rate, decreasing fertility, growth inhibitory activity on more than 400 insect species from different orders like Diptera, Hymenoptera, Coleoptera, Lepidoptera, orthoptera and Hemiptera etc [Ragsdale et al, 2004;Liu et al, 2004]. As neem extract is efficient to control several aphids in the field, so these are the most significant product to be used as biological pesticide.…”

“…The soybean aphid can also indirectly reduce yield by transmitting certain viruses [63]. Management of the soybean aphid is achieved mainly by selecting resistant cultivars and by applying synthetic insecticides [64]. When host resistance is not a viable option, organic producers have options to release natural enemies, such as parasitic wasps or ladybeetles, or they can use an organic-certified insecticide containing pyrethrum.…”

Soybean is the most produced and consumed oil seed crop worldwide. In 2013, 226 million metric tons were produced in over 70 countries. Organically produced soybean represents less than 0.1% of total world production. In the USA, the certified organic soybean crop was grown on 53 thousand ha or 0.17% of the total soybean acreage in the USA (32 million ha) in 2011. A gradual increase in production of organically grown soybean has occurred since the inception of organic labeling due to increased human consumption of soy products and increased demand for organic soybean meal to produce organic animal products. Production constraints caused by pathogens and insect pests are often similar in organic and non-organic soybean production, but management between the two systems often differs. In general, the non-organic, grain-type soybean crop are genetically modified higher-yielding cultivars, often with disease and pest resistance, and are grown with the use of synthetic pesticides. The higher value of organically produced soybean makes production of the crop an attractive option to some farmers. This article reviews production and uses of organically grown soybean in the USA, potential constraints to production caused by pathogens and insect pests, and management practices used to reduce the impact of these constraints.

“…Originally discovered in Wisconsin in 2000, this pest had already spread to three Canadian provinces and 20 US states by 2004 (Ragsdale et al 2004; see also Section 13c).…”

“…Rhamnus cathartica is considered to be ''the primary host species of most importance to the aphid's pest status in soybean'' (Voegtlin et al 2005). Within 4 yr, this aphid spread to three Canadian provinces and it was adapting to a large geographic area in the North-Central United States (Ragsdale et al 2004). More than 60 million acres of soybean are at risk to crop injury caused by this exotic insect and R. cathartica occurs over much of this area (Ragsdale et al 2004).…”

European buckthorn, Rhamnus cathartica L., is an introduced shrub or small tree of forests, thickets, open pastures, hedgerows, roadsides, and riparian habitats. In Canada, it is found from Alberta east to the Maritimes, but is absent from Newfoundland. It is particularly abundant in southern Ontario. Problems arise from its status as an alternate host for the fungi Puccinia coronata Corda. f. sp. avenae Eriks., which causes crown rust and leaf rust of oats and for Puccinia coronata var. hordei Jin & Steff., which causes crown rust of barley. It is also the overwintering host for the recently invasive soybean aphid, Aphis glycines Matsumura, which has been described as a serious threat to soybean production in North America. Prolific fruit production, in combination with extensive seedling establishment and shade tolerance, allows R. cathartica to dominate an understorey quickly. Its ability to tolerate a wide range of conditions, at least in fairly moist areas, may lead to further expansion of its Canadian range. Control strategies should focus on reducing populations in close proximity to oats, soybeans or barley and to reduce its abundance in areas of ecological importance.
