Slide 2

Limitations under the USDA's National Organic Program (NOP) Ingredients must be regular substances, or synthetics included on the National List (7CFR 205.600-205.607). Some common substances are likewise denied (idle fixings might be disallowed now and again – See EPA List 4A or 4B). All substances must be affirmed by the Organic Materials Review Institute (OMRI) as well as the state confirmation office. Assist limitations require precaution, social, and physical strategies (incorporates arrival of useful creepy crawlies) must be the principal decision for nuisance control. In the event that ineffectual, a plant, natural or manufactured on the national rundown might be utilized, if conditions are archived in the natural ranch arrange. This necessity mirrors a noteworthy work on depending on the utilization of natural and social practices, for example, trim pivot, broadening, territory administration, advantageous creature discharges, sanitation, and timing before falling back on restricted utilization of allowed vermin control substances.

Slide 3

Procedures and Methods in Adopting an Organic Management Plan Understand the irritations and gainful life forms that typically happen in the yield and suspect the vermin issues liable to happen. Bugs all the more viably controlled when numbers are low and right off the bat in their life cycles. Pay consideration on yield turns and harvest deposit joining, to stay away from development in irritation species. What assortments or products to develop When to plant, to keep away from vermin issues Good recordkeeping on nuisance issues – constructs an establishment for next seasons bother control procedures.

Slide 4

Procedures and Methods (proceeded with) Correctly recognize the nuisances and helpful life forms present and note when they happen generally usually. Cautions a producer to potential issues before harvest misfortunes happen. Utilize pheromones and other catching techniques when accessible for key bugs, to decide timing of populace cycles and foresee nearby increments in action. A few situations where mating disturbance can be utilized to forestall effective mating, and diminish consequent harming populaces (e.g. products of the soil bugs).

Slide 5

Procedures and Methods (proceeded with) Make visit or if nothing else week after week checks for nuisance action. Utilize a scope net, hand focal point, drop fabric. Investigate the underside of takes off. Distinguish middle of the road levels (activity limits) for nuisance movement in particular yields. Bugs nourishing straightforwardly on the consumable item can be endured a great deal not as much as defoliators by and large.

Slide 6

Specific Methods for Managing Arthropod Pests Organically Cultural control Mechanical control Biological control Chemical control

Slide 7

Cultural Control Coordinate planting and reap dates to stay away from specific bugs. Sweet corn and corn earworm Plant later products upwind of early harvests or plant them in detached fields. Utilize non-defenseless cover yields to enhance ripeness and give a wellspring of natural matter. Join a grass animal categories into a turn, these have a tendency to be impervious to numerous creepy crawly and sickness vermin of basic money crops.

Slide 8

Cultural Control (proceeded with) Plant field outskirts or strips inside the field of species or assortments that are not quite the same as the primary crop Flowering plants along fringes of fields can give living space and nourishment to useful creepy crawlies. Keep up a trap edit in an overwhelming state, so irritations may never need to leave Spray the trap trim in the event that they begin to leave (e.g. pearl millet) Manage overwintering locales for a large portion of the genuine bugs (stink bugs, squash bugs, horse feed weevils, and so on.) Lumber, box heaps, stockpiling structures, weedy field outskirts, and so on

Slide 9

Mechanical Control Soil Tillage and natural matter decay Allow a more extended decrepit period before planting, opens creepy crawlies to predators (e.g.- winged creatures) or expels sustenance supply for cutworms, wireworms, root hatchlings and certain parasites. Handpicking and vacuuming certain creepy crawly bothers in little plantings is entirely viable Tomato hornworms, lygus bugs, squash bugs, and so on. Bug hindrances can help in high esteem crops. Skimming column covers, plastic passages, intelligent mulches

Slide 10

Biological Control Many valuable life forms manage bug numbers in nature without the guide of chemicals. At the point when normally happening organic control is not satisfactory for keeping up a bug beneath levels that cause misfortunes, natural control can once in a while be expanded . Traditional organic control, Augmentation, Conservation and improvement.

Slide 11

Classical Biological Control Deliberate presentation and foundation of colorful normal foes into territories where they didn't exist. Normally against intrusive species. A few stages in doing this legitimately include: ID the nuisance's local range, hunt it's local range down applicants, deliver them into isolate offices for study to bar contaminants and affirm that no negative effects exist in the new nation, then at long last increment their numbers before discharge. Just Government offices or University Experiment Stations 100's of creepy crawly and weed illustrations have been fruitful. Vedalia bug on cottony pad scale, musk thorn weevil on musk thorn, desert flora moth on thorny pear prickly plant, and so forth

Slide 12

Augmentation Supplementing the quantities of actually happening common foes with arrivals of lab-raised or field gathered regular adversaries. Inoculative discharge – developing populaces of common adversaries sooner than ordinary, or building up it where it is not present. Discharging ruthless parasites in almonds or strawberries, mosquito angle in rice fields to control mosquitoes, arrival of bindweed bugs to control bindweed in wheat, and so forth

Slide 13

Augmentation (Continued) Supplementing the quantities of actually happening common foes with arrivals of lab-raised or field gathered characteristic adversaries. Inundative discharge – intermittent arrivals of common foes without any desires of foundation. So… . extra discharges will be required all through the season Releasing Trichogramma wasps for controlling caterpillar bugs, arrival of whitefly parasitoids (Encarsia) in the nursery, entomopathogenic nematodes utilized against a few soil staying creepy crawlies, and so forth

Slide 14

Tips for Releasing Beneficials Be certain to discharge an adequate sum. Ensure sufficient water is accessible before the discharge. Discharge life forms at dusk, to permit them an opportunity to locate a sheltered harborage Release in particular areas where pervasions are available. Utilize confines as well as valuable creepy crawly feast to keep bugs around if bugs are not present in adequate numbers. Give extra natural surroundings when conceivable (incorporates blooming plants and clover blends).

Slide 15

Conservation and Enhancement Modifying or improving the neighborhood environment to save helpful species or upgrading their exercises. Expanding plant differing qualities in the biological community (e.g. decrease monocultures). Requires watchful thought of the intricate collaborations amongst plant and creature populaces. Living space control with cover crops, substitute hosts, insectary plants, and soil supplements to monitor local regular adversaries.

Slide 16

Chemical Control If natural cultivators consider concoction treatment they may need to consider a few elements including: Mammalian danger, impacts on gainful species, satisfactory scope and volume, leftover movement. Every natural material, a hefty portion of which are botanicals, are not only more secure than customary pesticides (e.g. – Nicotine is one the most perilous substances known, yet it is viewed as a herbal bug spray, others like sulfur are great at smothering certain ailment issues, however may bring about skin as well as eye bothering). For the natural cultivator wishing to save advantageous creatures, botanicals and cleanser based items ought to be a final resort due to their expansive range abilities.

Slide 17

Chemical Control (proceeded with) Effects on advantageous creatures Indirect impacts through starvation of beneficials, which could incite their movement out of the field. Satisfactory Coverage Requires high volumes of water (100-200 gallons or more for every section of land) with thick coverings and with specific materials. May require more spouts and high weight to deliver the fancied bead estimate for ideal scope (Electrostatic or airblast sprayers). Appropriate Timing is key paying little heed to gear. Must hit a defenseless life form at its most powerless stage.

Slide 18

Chemical Control (proceeded with) Residual limit of most naturally endorsed materials is constrained – corrupt quickly in the earth. Rehashed applications might be important, so worry over resistance, however not as awesome with short lingering materials. Also, nuisances are probably not going to create imperviousness to materials, for example, oils and cleansers that utilization physical activities, for example, suffocation and entanglement.

Slide 19

Chemical Control (proceeded with) Pests controlled by naturally affirmed materials include: Aphids: oils, cleansers, pyrethrum/rotenone blends, kaolin dirt, Pyola ™(canola oil + pyrethrins) GE-determined?, garlic showers, diatomaceous earth, Beauveria bassiana (Mycotrol O) . May influence beneficials that are pulled in to honeydew. Permit time for slack in advantageous populaces before controlling aphids (e.g. greenbugs seldom require control past March 15 in southwest Oklahoma).

Slide 20

Chemical Control (proceeded with) Pests controlled by naturally affirmed materials include: Whiteflies: cleansers and oils (numerous applications), sticky traps, ocean growth powder, Beauveria bassiana (Mycotrol O). Careful scope under plant leaves fundamental. To start with search for parasitized whitefly pupae.
