Abstract
The present invention has introduced a kind of insecticide that contains margosic toxin, and its composition (weight %) is:
Margosic toxin 65-75
Nicotine 10-15
Stemonine 5-10
The sodium alkyl benzene sulfonate aequum
Margosic toxin gets from Radix Meliae skin and the extraction of bitter fruit leaf stalk.
Description
The invention belongs to field of pesticides, be particularly suitable for containing the field of pesticides of margosic toxin.Existing chemical synthetic pesticide, generally existing has serious pollution, people and animals is had damaging effect environment, and drug effect is relatively poor, and insect is had medicine resistance ability.
Task of the present invention, study exactly a kind of do not adopt chemosynthesis, drug effect height, environmentally safe, to people, animal do not have harm, to the natural type insecticide of insect nonreactive medicine ability.
In order to realize task of the present invention, the margosic toxin that the present invention adopts Radix Meliae skin and margosa stalk leaf to extract by alcohol solution dipping is that Main Ingredients and Appearance and nicotine, stemonine, sodium alkyl benzene sulfonate are with suitable ratio, form a kind of insecticide that contains margosic toxin, mix during use or with ammonium humate, or mix, or use separately with water.The composition (weight %) that contains the margosic toxin insecticide of the present invention is:
Margosic toxin 65-75
Nicotine 10-15
Stemonine 5-10
The sodium alkyl benzene sulfonate aequum
The extracting method of margosic toxin is with Radix Meliae skin after 1: 1 the pulverizing and bitter fruit leaf stalk, use 95% alcohol solution dipping, the temperature of soaking remains on 25～30 ℃, soak after 24 hours, squeeze and filter obtains the method that liquid adopts evaporation, after removing ethanol, superfluous liquid, adopt the adverse current rotary method to separate and obtain margosic toxin liquid, remove organic solvent with the method for distillation again and obtain margosic toxin.
Embodiment: on the three identical potted flower dried rhizome of rehmannia of various condition, half peanut ground is arranged from the seedling to the maturing stage, adding 42% humic acid ammonia with margosic toxin sprays seven times, there is the peanut ground of half not spray, output during harvest behind the injection margosic toxin is 81.5 jin, and the output of not spraying is 67 jin, and the fruit particle that sprays the back knot is big, full, the particle particle that does not spray is little.After the peanut ground warp sprayed secondary, two spotted spider mite all killed.By this example insecticide of the present invention is described, not only can also increases production by desinsection.
The pesticide that contains margosic toxin that utilizes the present invention to prepare, be injected on cotton and the green vegetable leaf, to cotton aphid, bollworm, cabbage caterpillar kill ratio more than 95%, also more than 95%, the present invention is not only good pesticide to the red spider kill ratio, and can also promote plant growth, precocity, high yield, show through 2 years experimental results of the inventor, tomato sprays the pesticide of margosic toxin of the present invention at Seedling Stage, and growth is fast, the result is many, the maturity period shortening. Peanut sprays pesticide of the present invention at Seedling Stage, can increase production 10 to 30%, and cotton, wheat, beans also have obvious effect of increasing production.
Raw material bitter fruit leaf stalk and root skin that the present invention is used, it is very abundant to originate, because margosa is a kind of wild plant, Ancient Channel of Huanghe River both sides and saline and alkaline area, on the south the Changjiang river there be the each province, and only just there are more than 300 ten thousand strains in Cao County, Shandong.
The present invention is a kind of pesticide of natural type, and environmentally safe does not have harm to people, animal, and insect is not had tolerance.
