A New Sorghum For Biofuels

Farmers may soon be growing a new type of energy crop, called high-biomass sorghum, that can be used to generate electricity or fuel cellulosic ethanol plants.

That’s according to Brent Bean, former Texas A&M research and Extension grain specialist and now director of agronomy at NexSteppe, a seed company that specializes in energy sorghums.

The company’s high-biomass sorghum is sold under the Palo Alto brand. Currently, one hybrid, N52K1009, is available, and more will be released this year, Bean told those attending the mid-December 2013 Western Alfalfa & Forage Symposium.

The hybrids typically grow between 12’ and 16’ tall and produce a great amount of biomass low in soluble sugar and typically “10-15 percentage points drier than a forage sorghum would be at harvest.” The lower moisture content reduces harvesting and transportation costs and gives the crop a higher energy density, says Bean.

The crop can be grown on marginal land, although it will yield better on productive ground. It will likely be harvested and stored as hay or silage, he adds. In a recent Oregon study, yields averaged 10 dry tons/acre under irrigation, with a yield range of about 6-13 tons, depending on the hybrid.

Spider Mite Control with Predatory Mites (Neoseiulus californicus)

Video: Spider Mite Control with Predatory Mites (Neoseiulus californicus)

The predatory mite Neoseiulus californicus is an effective natural enemy of various species of spider mites, including the two-spotted spider mite (Tetranychus urticae). As a key player in biological pest control, this predator helps growers protect their crops sustainably.

How does Neoseiulus californicus work?

•Specializes in targeting the larval and nymphal stages of spider mites.

•Also consumes spider mite eggs, ensuring population control.

•Detects prey through webbing and leaf damage rather than sight.

•Feeds by sucking out the contents of its prey.

Why use Neoseiulus californicus for spider mite control?

•Highly adaptable to different environments, including warm and dry conditions.

•Works as both a preventive and curative solution for spider mite infestations.

•Complements other predatory mites, such as Phytoseiulus persimilis, for integrated pest management (IPM).

•A natural, sustainable alternative to chemical pesticides.
