    "8/94/2M""The objective of this publication is to outline the options available for weed control in soybean production, define their advantages and limitations, and discuss the techniques and risks involved in using below-label herbicide rates."--Last paragraphMichael DeFelice (MU Department of Agronomy), Andy Kendig (University of Missouri Delta Center

    Control of perennial broadleaf weeds in Missouri field crops (1993)

    Get PDF
    Perennials are the most difficult weeds to control in field crops. Perennial plants survive, by definition, for more than two years and usually live for many years. Most perennial plants reproduce by seeds and by structures such as runners, underground structures that are difficult to eliminate. Satisfactory control of perennials usually requires a combination of cultural practices, herbicides and patience. This publication discusses the control of perennial broadleaf weeds

    "2/88/2M""The information in this guide is based on research conducted at the University of Missouri Agricultural Experiment Stations and elsewhere. It is written for the crops, soils, and weed problems of the state of Missouri. All herbicide information conforms to federal and state regulations at the time of writing. Consult the label attached to the herbicide container for current use precautions and restrictions. Use this publication as a guide in selecting and comparing herbicides. It is not a substitute for reading the product labels before use. The University of Missouri does not warrant commercial products and regrets any errors or omissions in this guide. Cost of herbicides was not considered in making these recommendations because prices vary with location and time. Herbicides may perform better or worse than indicated in this guide due to variability in the weeds infesting the field, rainfall, soil type, temperature, and many other environmental factors. Therefore, we have made no effort to list herbicides in order of preference."--IntroductionDepartment of Agronomy ; University of Missour

    Cotton weed control (1994)

    Cotton is a slow-growing plant, and only a limited selection of herbicides can be used for cotton weed control. These two factors sometimes make weed control difficult

    Mutations causing medullary cystic kidney disease type 1 (MCKD1) lie in a large VNTR in MUC1 missed by massively parallel sequencing

    While genetic lesions responsible for some Mendelian disorders can be rapidly discovered through massively parallel sequencing (MPS) of whole genomes or exomes, not all diseases readily yield to such efforts. We describe the illustrative case of the simple Mendelian disorder medullary cystic kidney disease type 1 (MCKD1), mapped more than a decade ago to a 2-Mb region on chromosome 1. Ultimately, only by cloning, capillary sequencing, and de novo assembly, we found that each of six MCKD1 families harbors an equivalent, but apparently independently arising, mutation in sequence dramatically underrepresented in MPS data: the insertion of a single C in one copy (but a different copy in each family) of the repeat unit comprising the extremely long (~1.5-5 kb), GC-rich (>80%), coding VNTR in the mucin 1 gene. The results provide a cautionary tale about the challenges in identifying genes responsible for Mendelian, let alone more complex, disorders through MPS

Ultimately, only by cloning, capillary sequencing and de novo assembly did we find that each of six families with MCKD1 harbors an equivalent but apparently independently arising mutation in sequence markedly under-represented in massively parallel sequencing data: the insertion of a single cytosine in one copy (but a different copy in each family) of the repeat unit comprising the extremely long (~1.5–5 kb), GC-rich (>80%) coding variable-number tandem repeat (VNTR) sequence in the MUC1 gene encoding mucin 1.

    "Perennials are the most difficult weed species to control in field crops. Perennial plants survive, by definition, for more than two years and usually live for many years. Most perennial plants reproduce by seeds and vegetative reproductive structures. These underground structures are the most difficult to eliminate. A combination of cultural practices, herbicides and patience is usually required to obtain satisfactory control of perennial weeds. This guide addresses control of perennial broadleaf weeds commonly found in Missouri field crops. Perennial grass weeds such as johnsongrass also occur in Missouri. Information for control of perennial grass weeds is available in other Missouri extension publications. Detailed weed descriptions and identification pictures are beyond the scope and available space of this guide. Weed identification guides are commonly available in libraries. Your local county extension office should be able to assist you in locating weed identification information."--First page.Michael S. DeFelice and Barry D.

    Aquatic weed control in Missouri (1988)

    Full text link
    "Aquatic plants are important components of lakes, ponds and streams. Aquatic plants aid in the prevention of erosion along shorelines and are a source of food and shelter for aquatic invertebrates, fish, fowl and game. Algae are the original source of food for nearly all fish and marine animals. Excessive growth of aquatic weeds not only interferes with fishing and boating but also causes problems with the intended use of ponds, streams, irrigation systems and drainage systems. Excessive weed growth: (1) creates health hazards; (2) interferes with navigation, fishing and other recreational activities; (3) impedes water movement and increases water losses; (4) destroys wildlife habitats; (5) speeds up the rate of silting; (6) causes undesirable odors; and (7) lowers real estate."--First page.Barry D.
