Deborah L. Freerksen - Hockessin DE

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

C25B 100
B01D 6242

US Classification:

2041828

Abstract:

Polydispersed, double-stranded and single-stranded polynucleotides are characterized according to their molecular size distribution. The polynucleotides are electrophoresed, stained, imaged and the image scanned and converted to pixel-by-pixel representations of the image density and size. The number and weight average molecular size are calculated along with the Z average molecular size.

Abstract:

The present invention relates generally to the control of pests that cause damage to crop plants. The invention relates to methods and compositions for enhancing invertebrate protection of a plant or reducing the development of resistance to diamides in invertebrates comprising the use of ryanodine receptor agonists. In some embodiments, this includes methods of using mixtures of ryanodine receptor agonists with other modes of pest resistance, such as other pesticidal compounds and/or transgenic pest resistant crop plants. Optionally, biological inoculants may be used to enhance overall plant health.
