Well balanced/managed soils and healthy crops can stand up to some pest pressure.

In part one we spoke of having flowering plants to attract beneficial insects.  We also need to plant the grounds of the land with perennial type of flowers the will start flowering as soon as possible in the region we live in and will continue all year or until first frost.

Make a chart of the flowering, trees, shrubs and flowers you have in the immediate area of your garden.  You will need name of flowering plant, when it starts to flower and when the flowers cease.  Once the chart is done you can see the holes you need to fill in to complete the flowering cycle of your garden/farm.  People living on 5 acres or more will use the flowering vegetation directly connected to their property.  Those of use that live in Urban or City areas will consider the flowering vegetation within one to two block radius of our garden.  If you have neighbors putting in gardens then consider moving your parameter closer to your garden as your neighbor may get more benefit from the flowering shrubs in their back yard than you will.  In Urban/City area it is a guessing game.  Do the best you can to put the beneficial plants in your own yard, maybe even your neighbor wouldn’t mind if you cultivate an area of their yard if you promise to keep weeded etc.

Find innovative ways to solve the situations. Washington growers Eric and Deanna Strandberg transitioned their 400 acres of apple and pear orchards to organic in part because they noticed that the conventional way of dealing with pests by spraying often just created more pest problems, requiring more spraying. Organic pest management, in contrast, seeks to protect beneficial organisms for the services they can provide.

In their first transition year, Eric asked neighboring householders with fruit trees if he could put crumpled up newspapers in the crotches of their trees to catch earwigs, which feed on the eggs of the pear psylla, the worst pear pest worldwide.”  The earwigs ue the newspaper during the day for a home and come out at night to eat the psylla..Case study by Rodale Institute.

 “Organic farmers have long maintained that synthetic fertilizers and pesticides make pest problems worse. Recent research has begun to support those observations. Plant susceptibility to insect feeding has been linked to high plant nitrogen levels, which in turn are related to the high soluble fertilizer inputs typical of non-organic agriculture. Free amino acids, again associated with high N applications, have also been reported to increase pest attacks. Compost-fed plants have lower soluble nitrogen levels and are thus less attractive to pests.” Rodale Institute.

“Systemic acquired resistance: Do plants have immune systems? Some scientists think the answer is yes. The term "systemic acquired resistance" refers to physiological changes that occur in plants in response to initial insect feeding or disease infection. These changes can help the plants stop the infection or slow insect reproduction rates. There's even evidence that crop plants under insect attack emit volatile scent signals to protect themselves or to communicate with insect enemies of the attackers.

 

Plant immune responses may also increase crops' nutritional value.    Researchers in California have found that unsprayed organic fruits produce higher levels of antioxidants—prized by health-conscious consumers—in response to insect and pathogen attacks.” Rodale Institute

Biodiversity has proven to be the best pest protection.  Creating environments for beneficals to live, selecting crops appropriate to your area and staying away from synthetic pesticides seems to work better all the way around.

“When choosing insectary plants, consider these criteria:

•        Select plants for their attractiveness to beneficial insects

•        Choose plants with an early and long bloom period

•        Select plants with low potential to host crop viruses or attract pest species

•        Choose plants with low potential to become weeds

•        Consider low seed cost and easy establishment

Many members of the Umbelliferae (coriander, dill, Queen Anne's lace), Compositae (goldenrod, yarrow, sunflower), Brassicaceae (sweet alyssum, wild mustard) and Leguminosae (sweet clover, alfalfa) plant families offer good floral resources for beneficial insects.

Among California vegetable growers, a popular insectary plant mixture is sweet alyssum, coriander, buckwheat and a cereal grain. (The cereal acts as a windbreak and as a host for alternate prey of the beneficials.) “ Rodale institute

PEST MANAGEMENT, PART ONE

Pest Management part 1, TSP part 10

 WEB SITE: DIY ORGANIC GARDEN

Pest management in Organic Systems requires a leap of faith.  Again, it is not surprising that soil health and conservation management are the main ingredients to managing pests.  Not all bugs and organisms are problems with crops and the more a person enhances their environment the more beneficial bugs and organisms move in to help the gardener/farmer with pest control.  Even chemical herbicides will not totally eliminate the destruction of enemies to your money crop.

Consider nature without the intervention of man.  The prairie grasses, grains and fruit tress fared well in the world before man started manipulating the environment for his own needs.  Organic methods simply advocate a return to nature; mimicking a natural environment for the benefit of your crop and in turn creates an environment that helps greenhouse gases, nutrition, pest management and the pocket book.  It is a Win Win.

One of the easiest ways to start off the process is to add winter cover crops to your garden.  These crops nourish your garden/fields, and can create over winter habitat for beneficial insects and animals.

As with weed management, identifying the pest is the first step.  Once you have identified the pest (destructive bug), identify it’s enemy (beneficial insect) and what the habitat is of the beneficial insect.  Add the beneficial habitat and watch for the results.

Many parts of the nation have aphid problems.  If you do, then identify the predator that eats them.  One such predator is the lady bug beetle.  You can buy a source of lady bugs or encourage them to stay year after year by creating habitat for them to stay in.  Ladybugs like woody areas, sticks, tall stands of grass or maybe that winter rye you just planted for a cover crop.  The tall ornamental grasses, instead of cutting them back for the winter leave them alone to create a safe haven for your over wintering bugs.

Lacewing are similar to lady bugs in what they devour and over winter in similar ways. Lacewings like Asters, cosmos, sunflowers, flowering dill and cilantro.  Lacewings also dine on aphids and other small larva.  Insects like ladybug and lacewings enjoy a snack of pollen related flowers that are small, flowers with small to no petal area with large pollen areas like the sunflower.

Wasps are another great garden guest.  The parasitic wasp will lay their eggs in larva and insects.  The eggs hatch and eat the larva from the inside out.  If you can keep a mud available to the mud dauber wasp they catch insects to feed to their young. Other wasp types like the small flowers.

Smaller flowers such as the alysum attract smaller insects such as syrphid flies to pollinate crops and are planted in rows around lettuces to help control aphids see cover crop alyssum.  In the picture are 3 rows of flowers to every 20 rows of lettuce.  Syrphid flies plant one or two eggs per plant, so they inoculate a large field of lettuce with aphid eating helpers.

Greater diversity of a complex landscape, higher percent of woody or herbaceious plants support a greater number of spiders…says carol O’meara of Colorado State University

Wheat fields in Germany with mulch created a habitat for spiders which reduced the cereal aphid population by 25%.

Spider are a great advantage to your crops and you can also change pest behavior, called spider caused abandonment, which causes cucumber beetles, Japanese beetles, moth and butterfly larva, leaf hoppers, plant hoppers to abandon that plant if they detect spiders.  Spiders kill more insects than then consume.

You will have more pests in un managed weedy areas but managed hedge rows and native perennials will inhabit more beneficial insects. Native annual and native perennial are more than likely to host beneficial insects where un managed weeds may be invasive weeds that attract pests.

See it in action on Pinterest.  Here I am creating a pictorial of plants and their benefits and how farmers are incorporating these plants into their crops or creating hedge rows to harbor the beneficials

Pre-emergent cultivation/ blind cultivation.

“The point of blind cultivation is to stir the top half inch of soil, adding air and causing the millions of tiny germinating weed seeds to dry out and die. The larger crop seeds are below the level of the cultivation and remain undamaged. Weed seedlings are at their most vulnerable at this stage. Effective blind cultivation will give you the biggest possible crop/weed size differential.” Rodale Institute

Other methods, such as timing can reduce weeds such as “Ohio organic grain farmer Dean McIlvaine waits until May or even early June to put in his corn crop. At this time the soils are warmer and plants grow more quickly, out-competing weeds. A delayed planting also gives McIlvaine time to make an extra trip with a disk or field cultivator to kill more germinating weeds.”

 Vegetative and synthetic mulches

“Mulches can be very effective at controlling weeds. Mulch changes the environment around the soil surface, making it difficult for weed seeds to germinate and grow. Vegetative mulches, such as rye straw, can also suppress weeds by allelopathy. Research shows that rye mulch can reduce weed seed germination by 75 to 95% while leaving large-seeded crops such as corn, peas, cucumbers or beans unaffected.   

Natural or non-synthetic mulches such as straw or leaves can have the additional benefit of boosting soil organic matter over time, and even adding fertility. Be careful whenever you import mulch (or compost) materials such as leaves, loose straw or grass clippings that you avoid potential contaminants or debris. Avoid glossy inks from newspaper inserts and magazine waste.

"Living mulches" are cover crops of clover, grasses or other species used to suppress weeds in orchards and some other types of cropping systems. These can be mowed regularly or seasonally to maintain the stand.”  Taken from Rodale Institute Organic Transition

“Livestock: Intensive rotational grazing is widely recognized for its effectiveness in limiting perennial weeds in pasture. But in some specialized systems, farmers have developed additional ways to use livestock for weed management. Chickens confined to small pens and rotated through fields have been shown to be effective at eradicating yellow nutsedge. Geese preferentially eat grasses, and so can be used to weed strawberry fields without damaging the crop. Some tree-crop farmers use sheep to graze the alleys between rows of trees or coffee bushes.” Organic transition, Rodale Institute

Research at the Rodale Institute, moreover, “has shown that organic crops actually have a greater ability to tolerate weeds than non-organically managed crops do. In almost 30 years of side-by-side trials, our organic plots have consistently yielded as well as our non-organic plots, even though the organic plots usually have heavier weed pressure. It may be that the organic crops suffer less competition from weeds because soil quality is better, making nutrient and water resources more plentiful.”

NonGMO base synthetic material is acceptable in Organic production but Organic farmers must prove that the two methods of

1. Cultural(crop rotation, sanitation, seed variety) Mechanical or physical (exclusion, beneficial insect habitat, lurs, traps, repellants, mulches, flame)
2. Natural biological, botanical or mineral inputs

did not work and it must be documented to prove they were ineffective.

It all goes back to soil health and conservation planning.  Know your weeds and which crops, cover crops and rotation cycles are needed to control the problems.

A good video put out by ATTRA not only addresses crop rotation but weed control in doing it. Youtube video  Organic Crop Rotation: Conservation Benefits
