Abstract:

The phytotoxicity and plant growth, the amino acid, protein and chlorophyll content of Brassica camptris L. were tested, which were treated with methylamino abamectin benzoate(MAB) EC 1% mixed with plant oil (such as refining pine oil with palm, refining pine oil, and palm oil) Substitute for xylene solvent, in order to explore the effect on safety of MAB mixed with plant oil substitute for xylene solvent to B. camptris. The results showed that no clear phytotoxicity to B. camptris of two kinds of MAB mixed with refining pine oil with palm and refining pine oil, while significant phytotoxicity to B. camptris were found , which treated with high concentration of two kinds of MAB mixed with palm oil and xylene solvent. The new irrecoverable misshapen leaf of B. camptris displayed by treated with MAB EC mixed with the xylene. While the young leaves withering and wilting were caused and the symptoms disappeared followed the leaves growth of B. camptris by treated with MAB mixed with palm oil. It is indicated that the protein content decreased significantly in B. campestris after treating with high concentration of MAB EC mixed with plant oils and the amino acid content increased by different concentration treatment. No effect to chlorophyll content and the growth of B. campestris were found. It is safety to B. campestris of MAB mixed with plant oil substitute for xylene solvent.
