EXTOXNET PIP - DCPA, CHLORTHAL, CLORTHAL-DIMETHYL
... slightly toxic to rainbow trout. The compound is practically nontoxic to estuarine and marine organisms (invertebrates and some fish). The available data suggest that DCPA poses no hazard to endangered aquatic ... essential for degradation. In one study, there was no apparent buildup of pesticide residues in soil even after repeated application. The DCPA concentration declined slowly to 75 or 80% in 28 ...

EXTOXNET PIP - MCPA
... freshwater invertebrates, and estuarine and marine organisms. Effects on other organisms: It is nontoxic to bees, with a reported oral LD50 of 104 ug/bee [5,6]. Environmental Fate: Breakdown in soil ... of 14 days to 1 month, depending on soil moisture and soil organic matter [21]. Decreased soil moisture and microbial activity, as well as increased soil organic matter, will prolong the field half-life ...

EXTOXNET PIP - AMITROLE
... freshwater invertebrates [18]. Effects on other organisms: Amitrole inhibits the growth of bacteria [16]. It is nontoxic to bees [6]. Environmental Fate: Breakdown in soil and groundwater: Amitrole has low soil ... has a moderate potential for groundwater contamination because it does not adsorb strongly to soil particles and is readily soluble in water. Breakdown in water: In aquatic environments, ...

EXTOXNET PIP - AMMONIUM SULFAMATE
... on rainbow trout and aquatic invertebrates [8]. Effects on other organisms: Deer were not harmed when they were fed AMS-treated leaves [28]. Environmental Fate: Breakdown in soil and groundwater: Ammonium sulfamate has a low to moderate persistence in soil and can be decomposed by soil microbes in a 6- to 8- ...

EXTOXNET PIP - AZINOPHOS-METHYL
... rapid succession [8]. Azinphos-methyl is highly toxic to aquatic invertebrates, shellfish, frogs, and toads [8]. The LC50 values are ... [27]. Environmental Fate: Breakdown in soil and groundwater: Persistence of azinphos-methyl in soil is quite variable but is generally low ... days. Azinphos-methyl is fairly immobile in soil because it adsorbs strongly to soil particles and has low water solubility. ...

EXTOXNET PIP - BENOMYL
... Introduction: Benomyl is a systemic, benzimidazole fungicide that is selectively toxic to microorganisms and to invertebrates, especially earthworms. It is used against a wide range of fungal diseases of field ... other organisms: A single application of benomyl to turf grass can substantially reduce some soil dwelling organisms. The compound is very lethal to earthworms at low concentrations over a ...

The calculated bioconcentration is low and it is not ... be carried off site with sediment or dust. The rate of application, temperature, soil organic matter, and soil acidity can all affect its breakdown. Bensulide leaches very little in sand, clay, or ...

EXTOXNET PIP - BENTAZON
... coldwater and warmwater fish. Bentazon is slightly toxic to aquatic invertebrates. The LC50 (96-hour) for bentazon in rainbow trout is ... [8,70]. Environmental Fate: Breakdown in soil and groundwater: Bentazon has a low persistence in soil. Its half-life is less than 2 ... the sun and rapid degradation by soil bacteria and fungi [8]. Bentazon does not bind to soil particles and it is highly soluble in ...

EXTOXNET PIP - BROMACIL
... toxic to aquatic invertebrates [8]. Effects on other organisms: Bromacil is not toxic to honeybees [1]. Environmental Fate: Breakdown in soil and groundwater: Bromacil binds, or adsorbs, only slightly to soil particles, ... and long exposures to sunlight, there is very little loss of bromacil from dry soil. It does not readily volatilize, nor does it break down in sunlight [8]. Laboratory ...
