Specialty crop herbicides are not a priority for the agrochemical industry, and many of these crops do not have access to effective herbicides. High-value fruit and vegetable crops represent small markets and high potential liability in the case of herbicide-induced crop damage. Meanwhile, conventional and organic specialty crop producers are experiencing labor shortages and higher manual weeding costs. Robotic weeders are promising new weed control tools for specialty crops, because they are cheaper to develop and, with fewer environmental and human health risks, are less regulated than herbicides. Now is the time for greater investment in robotic weeders as new herbicides are expensive to develop and few in number, organic crops need better weed control technology and governments are demanding reduced use of pesticides. Public funding of fundamental research on robotic weeder technology can help improve weed and crop recognition, weed control actuators, and expansion of weed science curricula to train students in this technology. Robotic weeders can expand the array of tools available to specialty crop growers. However, the development of robotic weeders will require a broader recognition that these tools are a viable path to create new weed control tools for specialty crops.

“…The ability of specialty crops to remain cost-competitive with field crops depends, in part, on research and development, and perhaps the use of biotechnology [12], and yet is unclear how the public views the use of biotechnology in such crops. Ultimate success or failure of agricultural biotechnology may rely less on regulatory processes or information provision [13] and more on market acceptance as a result of the benefit provided by a GE food [14,15] and how the benefits are discussed and communicated by scientists [16,17]. Psychological research reveals that public perception of risk often diverges from informed experts [18], and perceived riskiness is a function of perceived (lack of) benefits and perceived necessity of the technology [19,20].…”

“…For example, a transgenic product with modifi cation in endosperm of a hybrid such as maize should be deployed in the female parent to maximize the dosage eff ect of the gene in the endosperm (3n) tissue (Zhong, 2001). High research inputs, regulatory issues, small acreages planted, and diversity of varieties are serious limitations for adoption of transgenic horticultural crops (Alston, 2004). Stacked Bt products with Cry1Ac and Cry2Ab for insect control in cotton have been developed because models have shown advantages of such pyramiding varieties for insect resistance management (Shelton et al, 2002).…”

Transgenic Breeding: Perspectives and Prospects

et al. 2009

Transgenic technology serves to introduce gene sequences for expression of a desired trait. Production of transgenic plants is reported in many crops, but commercialization is limited to a few selected crops, such as cotton (Gossypium hirsutum L.), corn (Zea mays L.), soybean [Glycine max (L.) Merr.], and canola (Brassica napus L. and B. rapa L.). This paper presents the sequential processes of transgenic event design, event selection, and “cleaning up” genetic background for forward breeding programs. Expression of the foreign gene cannot be viewed in isolation and is more complex than has been assumed because of the interaction of transgene with native genes. Variations among clones and within the progeny are observed, and hence all the clones are taken into account for evaluation. Plant breeding must be involved to move transgenes from transformable but agronomically unacceptable genotypes into elite breeding lines with two backcrosses. Production of transgenic plants in large numbers is difficult and laborious and requires large investments. It is worthwhile investing in parallel efforts to incorporate the transgene into improved plant material to satisfy commercial interests.
