The recent removal of fenamiphos from availability leaves golf course superintendents with no effective management for plant parasitic nematodes. Fenamiphos was the only effective nematicide registered for use on golf greens in the United States. However, the LD50 of fenamiphos is in the single digits and therefore difficult and risky to applicators and non-target organisms. There have been a number of commercially-available products and experimental products offered as fenamiphos-alternatives.

Preharvest drop of fruit can result in losses to a grower that may exceed 50% of the total crop. There is a need to find effective ways to keep fruit on the tree until it achieves an acceptable level of quality and maturity. Compounds that can potentially be used to influence preharvest drop are also known to affect ripening and fruit quality. Therefore, the effect of strategies that control preharvest drop must also be evaluated for their effects on fruit quality and storage potential.
To strengthen the rural economy, successful strategies are always needed to reduce farm production cost and increase product values. Organic waste is generally disposed of by being left on the field to decay and/or burned. These treatments yield low values and may cause environmental pollution. Production and use of bio-oil and biochar from organic wastes could improve soil and environmental quality, provide renewable energy and reduce fossil fuel dependency, and increase soil carbon sequestration and mitigate global warming.
With the rapid development and wide application of nanotechnology, the introduction of manufactured nanomaterials into both solid and liquid wastes (and to the environment) is inevitable through production, use, and disposal. It has been reported in 2008 that nano-TiO2 is leached out of house facades into receiving surface waters. Currently, there are over 800 products on the market containing nanomaterials such as lotions, sunscreens, paints, and socks. This research will determine the environmental behavior and process of several types of manufactured nanomaterials.
With increased pressure to utilize more practical, ecological and economically feasible strategies in the management of turfgrasses, additional research is needed to identify best management practices aimed at preservation of water resources.
