Edelstein, Mark, Co-Publisher has reference to this Academic Journal, PHwiki organized this Journal Pesticides in addition to the Environment ASM 336 Pesticides Goal: to stop or limit pest occurrence Types: Insecticides kill insects Herbicides kill weeds Fungicides suppress or kill fungi Benefits Allow agricultural producers to improve the quality, quantity, in addition to diversity of our food supply. Used in timber, turf, horticulture, aquatic, in addition to structural pest control industries. Homeowners in addition to home gardeners often use pesticides in their homes, yards, in addition to on pets.

What Happens after Application When pesticides are applied the goal is that they will remain in the target area long enough to control a specific pest in addition to then degrade into harmless compounds without contaminating the environment. Once applied, many pesticides are mobile in the environment (air, soil, water). This movement can be beneficial (moving pesticide to target area, such as roots) but can also reduce the effect on the target pest in addition to injure nontarget plants in addition to animals. Pathways of pesticide movement Runoff Chemical degradation Volatilize (gas vapor) Leaching in addition to breakdown in soil Leaching in addition to degradation by microbes Photo degradation (sun) Factors influencing a pesticides fate Properties of the pesticide Conditions where & when applied Application method
Properties of the pesticide Vapor Pressure (volatility) pesticides with a high vp are more likely to change to a gas in addition to escape into the atmosphere. Sorption attraction to soil surfaces, pesticides with higher sorption values have reduced leaching Properties of the pesticide Water Solubility/dissolvability – more soluble pesticides have lower sorption in addition to are more mobile in the environment as they are leached or moved with runoff. Persistence the amount of time a pesticide remains in the environment, measured by half-life. Pesticides with longer half-lives pose a greater threat to the environment. Conditions where & when applied To maximize pesticide effectiveness in addition to minimize negative environmental impacts, the pesticide must be compatible with the physical, chemical, in addition to biological conditions of the application site. For pesticides use in crop or plant pest control consider the following conditions: Soil: physical in addition to chemical properties (texture, amount of organic matter, pH).
Conditions where & when applied Geology depth to water table (larger distances give more soil to act as filter) Surrounding water sources nearby water is more susceptible to contamination when pesticides are applied to highly erodible soils, over-irrigated, or rain-soaked soils. Managing crop residues in addition to maintaining grass waterways in addition to filter strips help to protect surface waters from sediment in addition to pesticide pollution. Conditions where & when applied Environmental conditions heavy or sustained rainfall or irrigation shortly after pesticide application can increase runoff, leaching, in addition to volatilization. Soil temperatures (extremely high or low) can interfere with pesticide per as long as mance. Pesticides generally become more volatile in high temperatures in addition to windy weather. Pesticides can be incorporated (disked in) or applied directly into the soil to decrease the potential as long as drift in addition to volatilization. Application method The challenge as long as pesticide applicators is to maximize the benefits of pesticides through sound management while reducing environmental risks. This includes: Keeping current of the latest in as long as mation. Taking all necessary preventive measures, including transportation, secure storage, proper disposal of containers in addition to rinsate, in addition to spill prevention. Furthermore, avoid sensitive areas such as sinkholes, depressions, wells, surface water, public institutions in addition to private buildings.
Product labels The pesticide label is a binding, legal document. Compliance is required by state in addition to federal regulations. Label directions must be carefully followed from purchase to container disposal. High risk pesticides may only be purchased in addition to applied by certified persons. Pesticide Use Careful selection as long as a specific pest underst in addition to the pest, site, product, in addition to risks.
