Possibly • What’s the best way to get rid of Bermuda grass? Repeated applications of Glyphosate to start a new bed; hand pull invaders creeping into an established bed • Can I use vinegar as a spray to stop bugs on my plants? No – vinegar can harm your plants • Can I use egg shells to plant starters? No. • Can you recommend something to buy to test your own soil? Lab tests are much more reliable. 3 Questions from SVG1 • When buying seeds are there certain ones better than others – i.e. organic? Depends on what “better” is. • How do I keep bunnies out of my plants? Fencing • Small scale composting tumblers vs. bins – tumblers are less efficient – worms might be a better option • Vermiculture – VCE Pub & lots of good books, see Brenda • How did the chickpeas grow? They did alright– the squirrels seemed to enjoy them 4 Questions from SVG1 • More detail on raised beds and orientation to the sun – orient so that you get as much sun for as much of the day as possible, an E-W orientation is more common than N-S • Growing Wheat for Bread – Pub 424-024 Bread Wheat in VA • Starting seeds – more of an advanced topic, see SVG 2 presentation from 2015 on MGPW.org • More information on smaller suburban gardens – Principles in this class series apply to all gardens • More detail on starting in the spring – we get into that today 6 Planning Your Garden – What to Plant and When • Plant Families and Crop Rotation • Vegetable Planting Calendar and Succession Planting • Garden Journaling 7 Vegetable Families • Legumes * • Alliums • beans, peas • onions, garlic, shallot • Crucifers * • broccoli, radish • Chenopods • Cucurbits * • spinach, beet, chard • cucs, squash • Composites * • Solanaceous * • lettuce, artichoke, • tomato, pepper endive, greens • Umbels • Grasses * • carrot, parsnip, cilantro, dill • corn, cover crop grains * Rotate every year, 3-4 year cycle 8 Legumes Characteristics Members • Fixes Nitrogen in Soil • Peas Stimulates beneficial soil Cowpeas • • organisms • Snap beans • Dry beans • Uses Phosphorus and Manganese • Soybeans • Clovers • Follow a “heavy feeder” • Vetches - Tomatoes • Fava beans - Corn • Winter peas • Alfalfa Crucifers/Brassicas Members Characteristics • Broccoli • Prone to Club Root disease Cabbage • Pests: Cabbage Loopers, Cauliflower • • Imported Cabbage Worms, Collards • Harlequin bugs • Brussels sprouts • Kale • Good Cover Crop for • Mustard Nematode control • Chinese cabbage • Radishes and Mustards are • Radish good early trap crops • Rutabaga • Cool Season • Turnips Curcurbits Members Characteristics • Cucumber • Pests: Squash bugs, • Squash Squash Borers, • Melon Cucumber Beetles • Gourd (spotted and striped) • Pumpkin • Diseases: Bacterial Wilt (mainly cucs and melons) • Generally warm season Solanaceous Members Characteristics • Tomato • Heavy N feeders – follow • Pepper legumes?

  • Ecology of Interactions Between Weeds and Other Categories of Pests
    WEED SCHOOL 2002 Ecology of Interactions between Weeds and other Categories of Pests Robert F. Norris Vegetable Crops and Weed Science Department, University of California, Davis, CA 95616 Introduction The term pest includes pathogens, weeds, nematodes, mollusks, arthropods, and vertebrates. One category of pests does not occur in the absence of pests in other categories, yet most IPM systems are designed around a single category of pest. For full implementation of IPM it is essential that all categories of pests be managed in an integrated manner. Allowances for the interactions that occur between the categories of pests be incorporated into the IPM decision making process. Interactions between pest categories can be diagrammed in the form of a 'pest hexagon' (Figure 1). Not all interactions between all categories of pests are of equal significance, but due to the trophic position of weeds in the ecosystem weeds have the potential to impact all other categories of pests. Weeds presence in agricultural systems can vary from essentially none in a highly managed monocropping system, such as that used for cotton in the San Joaquin valley, to very diverse mixture of species in small field cropping systems interlaced with hedges, fence lines, stream banks, and woodlands. Such contrasting agricultural systems provide very different habitats for all other organisms present in the systems. At the farm level there is a large difference in habitat for all organisms between fence lines that are weedy and those that are maintained weed free. Similarly, within orchards there can be large habitat differences between those managed with a weed-flee floor versus those managed with vegetation cover.

The pests that attack plants produced under conventional greenhouse practices also infest plants produced in float systems.

  • Chapter 9 Biological Control and Integrated Pest Management
    Chapter 9 Biological Control and Integrated Pest Management David Orr Abstract The manipulation of beneficial organisms remains a very important tool in integrated pest management programs of insect pests worldwide. This chapter describes the approaches to using biological control and a historical perspective of each. Recent developments in genetics, systematics, population dynamics, pesticide chemistry, and public opinion have led to increased scrutiny and inclusion of ben- eficial insects into IPM programs. This chapter describes these developments and the variety of approaches that have been used to implement biological control as a useful tactic in IPM. It also describes how biological control interacts with other IPM tactics, and the potential for better integration into IPM programs. Keywords Beneficial organisms · Importation biocontrol · Augmentation · Conservation biocontrol · Predators · Parasitoids 9.1 Introduction Biological control has been a valuable tactic in pest management programs around the world for many years, but has undergone a resurgence in recent decades that parallels the development of IPM as an accepted practice for pest management. This chapter is not intended to be an exhaustive review of research involving biological control. Instead, it will try to focus on implementation of biological control practices in insect pest management programs. It will begin with an overview of the general concepts and challenges facing the use of beneficial organisms within each of the general approaches to biological control. A brief historical perspective of biological control follows. Next, the interaction of biological control with the various elements of integrated pest management programs is considered. Existing implementation, as well as potential uses of biological control in IPM are also considered.

"#$%&!'())! ! !*+,-#./#012!34$.%+1-+$2!5.-2$#-+$2!627.28! Cropland Policy The mission of Boulder County Parks and Open Space (BCPOS) is to conserve natural, cultural, and agricultural resources and provide public uses that reflect sound resource management and community values. The Department manages 25,000 acres of agricultural land 18,000 of those acres are managed as cropland or irrigated pastureland. BCPOS is in the process of developing a cropland policy to guide management of these lands. The Cropland Policy will tie the Department’s daily management practices and the County Comprehensive Plan’s broad directives regarding the management of open space and agricultural land. The policy will outline the guiding principles staff will use to make management decisions on open space properties managed as cropland. Defining these principles will streamline decision-making processes during planning and make it easier for open space tenants and the residents of Boulder County to understand the goals of our cropland program. Visit the department’s webpage at www.BoulderCountyOpenSpace.org for more information. About this Report This literature review will examine sustainable agriculture practices in an effort to inform the discussion for Cropland Policy for Boulder County Parks and Open Space. It will explore some of the challenges faced by producers and ways in which producers can continue to take a leadership role in making their operations and their communities more sustainable. Agriculture is a critically important part of Boulder County. It helps to keep land as open space, preserve the rural culture, and increase the economic security of the county and its residents.
