Some organisms release toxins or otherwise change conditions so that pest activity or growth is reduced. Mostly molds or bacteria. Occasionally fungisides are used in seed coatings or a diverse range of nematodes or pathogens will help limit numbers of damaging species.
Defoaming agents
Some pesticide mixtures produce copious amounts of foam as a result of the action of hydraulic or mechanical agitaitors. These agents eliminate foam in the spray tank.

What mode of action should you use if insect populations are breeding rapidly?
Sterilant
Cationic surfactants
Strongly attracted to plant surfaces, so are highly phytotoxic when not blended with other types of surfactants.
Signs of disease
Structures that the pathogen may produce on the surface of the hose, such as mycelia, sclerotia, sporophores, fruiting bodies, and spore.
Viral symptoms
Stunting, tissue deformities, chlorosis, and vein clearing
Stickers
Substances such as latex or other adhesives that improve pesticide attachment to sprayed surfaces. Protect applications from washing off in rain, high wind, or leaf abrasion. Incorporate ultraviolet inhibitors to slow breakdown in sunlight.
Disc-core
Suitable for high-pressure and high flow rate applications of insecticides and fungicides
Surfactants
Surface-active agents known as wetting agents or spreaders that enhance spray coverage by reducing surface tension of spray droplets. Ex) Cottonseed oil and soy oil for coverage on waxy or hairy surfaces. Measured in dynes/cm - water is at 72 dynes/cm, optimal for sprays is about 30 dynes/cm.
Carbamates
Synthetic organic pesticides derived from carbamic acid that impair nerve function and are highly toxic to mammals, including human beings. Ex) Carbaryl (sevin), methomyl (lannate), metam-sodium, and metam-potassium.
Lower developmental threshold
Temperature below which development stops
Soil properties affecting leaching potential
Texture and structure - permeability and porosity Organic matter - high OG means uptake Depth - Shallow bodies increases chances of leaching Geology - Permeability of the geologic layers lying between the surface of the soil and the groundwater
Nozzles clog repeatedly
The agitator is not working properly
Threshold limit value
The airborne concentration in ppm of a chemical that produces no adverse effects over time.
Collar region
The area on the outer side of the leaf where the blade and the sheath join.
Sprayer pressure too high
The bypass system has become resistricted
Tolerance
The highest residue level of a particular pesticide that is legally allowed on a particular commodity. Tolerances for a pesticide are set by the U.S. Environmental Protection Agency and are based on crop residue trial data and the potential risks the pesticide poses to human health.
Selecting surfactants consider the following
The nature of the target surface The physical and chemical nature of the pesticide Whether the pesticide has contact or systemic action Weather conditions and cultural practices The biology or habits of the pest
Excessive drift
The nozzles are positioned too far from the target
Sprayer pressure too low
The nozzles have become worm
Instar
The period between molts in larvae of insects. Most larvae pass through several instars; these are usually given numbers such as first instar, second instar
Aerosols
The pesticide combines with a chemical propellant (petroleum oil carriers) in the can to emit a fine airborne mist or fog.
Directions for use
The place to look for pests that the manufacturer claims are controlled when exposed to the pesticide, as well as specific sites, plant species, or animals to which the product may legally be applied

Adsorption
The process whereby a pesticide binds to soil particles
Allelopathy
The production of chemicals by plants that inhibit the growth of neighbouring plants. Ex) black walnuts produce a toxin that inhibits growth of plant species around the base of the tree.

Amaranth family
Upright, broad-leaved, herbaceous plants that can be annual, biennials, or short-lived perennials. Can reach 8 ft in height. Have small, inconspicuous greenish flowers, cotyledons are narrow and elongate and are 4-5x as long as they are wide. Can cause nitrate poisoning in livestock. "Pigweeds"
Air carrier sprayers
Use fans or blowers to generate airflow that assists in moving the spray to the target. Use hydraulic or air-shear nozzles to generate spray droplets. Hydraulic nozzles use pump pressure and nozzle design to produce droplets. Air-shear use high-velocity airflow from the sprayer fan to atomize low-pressure liquid streams.
Power dusters
Use fans powered by electric or gasoline motors. Either battery powered or plug into a standard electrical outlet. Used to apply dusts in date palm gardens and to row or vine crops.
Sweep nets
Use to collect adults and larvae or nymphs of invertebrate species that are free-living on foliage

Geese
Used for controlled weedy grasses in cotton, orchards, and vineyards
Roller
Used for herbicide applications of flowable, emulsifiable concentrate, soluble powder, or other nonabrasive formulations

Batch tank injection
Used for long injection periods. Bad if a constant injection concentration is required.
Extended range flat-fan

Air assist sprayers
Used in agronomic row crops or with smaller trees and vines.
Disc-core nozzles
Used in air blast sprayers. Suitable for high-pressure and high-flow rate application of insecticides and fungicides. Contains a spinner plant also called a core which produces a high rotation speed of the liquid into the whirl chamber. Produces a hollow cone spray pattern. Used for high-pressure and high-flow-rate applications of insecticides and fungicides

Flowables (F)
Used when the a.i. is an insoluble solid and will not dissolve in either water or oil. Combine finely ground pesticide particles with a liquid carrier and emulsifiers to form a concentrated emulsion. Require agitation and leaves visible residues. Easy to handle as a liquid but subject to spilling and splashing like ECs, abrasive to nozzles and pumps, and settle out in their containers. In containers <5 gals to make remixing easier.
Mechanical dusters
Uses a fan and agitator or a level-operated bellows to force dust-laden air out of a hopper.
Quantitative fit test
Uses an electronic particle detector to measure the particles in the room and the particles present inside the respirator as the person performs movement and breathing tests.
Center-pivot
Water usually pumped from underground and sprayed from mobile boom with sprinklers.
Dry flowables (DF)
Water-dispersible granules mixed with water. Granules have a higher % of a.i. per UOM because manufacturers use less carriers. Simple to mix and no dust involved, measured by volume. Require constant agitation.
Water-soluble concentrates or solutions (S)
Water-soluble concentrates or solutions that dissolve in water, similar to sugar-based syrups. Does not require agitation and non abrasive to equipment.
Runoff
Where pesticide residues are carried in runoff water to more direct routes to ground water such as: Dry or drainage wells Poorly sealed production wells Soil cracks
Vetch
Widely distributed purple-white herbaceous plant used to improve biological control of mealybugs in vineyard. Supplies ant's with nectar which keeps them from interfering with parasitic wasps which control mealybugs.
Swath width
Width of the boom plus the distance between each pair of nozzles. Adjust boom height so that there is approximately a 30% overlap of spray from adjacent nozzles on the boom.
Timing of planting reduces insect and disease management
Winter-grown carrots and potatoes can be planted when the potato cyst nematode is not active. Black root rot can be avoided in cotton by planting later to reduce the chance of infection. In beats, beet yellow virus and beet mosaic virus have been kept under control by following stict planting programs that allowed no early-spring planting in or next to growing districts where sugarbeets were overwintered.
Sulfonylureas
Work on a braod range of grasses and broadleaved weeds but do not affect plants they are designed to product. High possibility of resistance which disrupts protein synthesis or acetolactate synthase. Ex) Rimsulfuron, sulfometuron methy, and chlorsulfuron.
Powered backpack sprayer
