The biosynthesis of PSMs in the plants are affected by several biotic and abiotic factors; however, their concentrations are also affected by other factors. The location/region can alter the content of secondary metabolites in plant species thus, interrupt the assumed activities of plants (Badoni et al.,Gupta et al.,Yang et al Cited by: Abstract.

Seven factors are known to influence the fate and behavior of pesticides in soil systems: (1) chemical decomposition, (2) photochemical decomposition, (3) microbial decomposition, (4) volatilization, (5) movement, (6) plant or organism uptake, and (7) by: Environmental and cultural factors affecting the persistence and efficacy of fungicides on golf course turfgrass.

By environmental, and toxicological consequences and their use should be limited when possible. Research was conducted to determine the factors that influence degradation of the common turfgrass fungicides.

Plant growth is often measured as a change in area, length (h), volume, height, wet or dry weight. These methods may not always be a satisfactory measure of growth at a particular stage of plant development, i.e, a germinating seed may show an overall loss in dry weight due to the utilization of food reserves during respiration, although the seed is definitely growth as evidenced by its.

A second group includes the environmental factors, particularly temperature, precipitation (and humidity) and air movement (wind). The other factors depend on the properties of the plant or soil. Characteristics influencing the persistence of pesticides in plants include the plant species involved, the nature of the harvested crop, the Cited by: Physiological variations, environmental conditions and genetic polymorphisms, along with the interactions of these three factors, are known to determine specialized metabolite content in plants.

The first group is the active ingredi-ent(s) and the second is the inert or inactive ingredients. The combina-tion of active and inactive ingredients is known as the pesticide formulation. Leaves of plants exhibiting this diurnal leaf movement intercept significantly more herbicide when applications are made during the day rather than when applied in the evening or early morning.

Thus, reductions in herbicide interception may be responsible for poor control with night applications in some situations. Full text Full text is available as a scanned copy of the original print version.

Several factors that affect pesticide movement are discussed below. The importance of these factors to leaching varies with each situation. A single factor may be more important than another in one situation and of very little consequence in the next. The diagram below shows how different factors can effect pesticide absorption into water sources.

Numerous environmental factors might affect the conformational, aggregation, and cytotoxic properties of IAPP.
