phytotoxicity

However, due phytotoxicity and high value their use became unpractical.

Phytotoxicity is a toxic effect by a compound on plant growth.

Both of these species have been studied extensively for use in phytotoxicity tests.

These oils are enviromentally safe and they have little phytotoxicity to the plants.

Multiple applications in a short time interval can aggravate phytotoxicity.

The germination index can be used as an indicator of phytotoxicity in soils.

In addition, water conditioning agents can increase phytotoxicity.

Assessment of the possible phytotoxicity of a substrate using an easy and representative biotest.

This included a high proportion of paraffinic hydrocarbons and purification that allowed year-round use without phytotoxicity.

The fertilizer product has a distinct odor, and because it contains no chemical salts, it can be applied without concern for phytotoxicity.

Plants that are predominantly low to the ground or freshly planted are the most susceptible, and the phytotoxicity may prevent germination of some seeds.

Phytotoxicity and maturation and the possible tie up of nitrogen by incompletely decomposed lignin.

Their low phytotoxicity and lack of biological significance in human physiology has provoked a fairly small amount of interest in these compounds.

Compost: This should be fully composted material to avoid possible phytotoxicity problems, and the weed seed must have been eliminated, otherwise the mulch will actually produce weed cover.

Insecticidal soaps may cause phytotoxicity (toxic to the plant) symptoms, such as yellow or brown spotting on the leaves, burned tips or leaf scorch on certain plants.

Quantitative uptake by surface runoff of pesticides and other contaminants has been studied since the 1960s, and early on contact of pesticides with water was known to enhance phytotoxicity.

Latterell's classic paper was "Differential Phytotoxicity of Metabolic By-Products of Helminthosporium victoriae" published in Science, v. 104, pp.

His current research focuses largely on the phytotoxicity of trace metals in soil solutions, giving particular consideration to aluminium and other trace metals such as Pb, Cu, Zn, and Ni.

Although metabolites of urea are nitrogen fertilizers, it is easy to over-fertilize with urine, or to utilize urine containing pharmaceutical (or other) content, creating too much ammonia for plants to absorb, acidic conditions, or other phytotoxicity.

Of the seven phytotoxins isolated in fungal leaf spots from sugar beet (Beta vulgaris), betaenone B showed the least amount of phytotoxicity showing only 8% inhibition of growth while betaenone A and C showed 73% and 89% growth inhibition, respectively.
