Description
Technical field
The present invention relates to a kind of vegetable insecticide-Radix Rhapontici seu Radix Echinopsis insecticide and manufacture method thereof that is used to prevent and treat larvae and vegetable-crop pest-insect.
Background technology
Chemical pesticide is human control farm-forestry crop insect, captures the important means of grain good harvest.But because people are to its long-term, a large amount of irrational uses, and the intrinsic defective of some medicament itself, caused that insect develops immunity to drugs, insect serious problems such as wildness, pesticide residual contamination environment again.
Under this background, be object with the natural plant product, seek bioactivator, research and development novel plant agricultural chemicals has great importance.Vegetable insecticide meets the requirement of environment reasonability agricultural chemicals, has its degradation pathway smoothly at natural world, and environment is not had negative effect, is the trend and the trend of current agricultural chemicals development.
Radix Rhapontici seu Radix Echinopsis (Echinops latifolius) has another name called blue tartar, radix echinopsis latifolii, is the composite family herbaceos perennial, and main product is in the ground such as Hebei, Liaoning and Shaanxi of China.On the Chinese herbal medicine its effect is classified as clearing heat and detoxicating, detumescence and apocenosis and the logical muscle of lactogenesis etc.And we find that the Radix Rhapontici seu Radix Echinopsis root extract has significant stomach toxicity, action of contace poison to insects such as cabbage caterpillar, diamond-back moth and larvaes in a collection of vegetable active is followed the trail of the test of screening, so system research its insecticidal action mechanism.And on this basis, its development is vegetalitas Radix Rhapontici seu Radix Echinopsis insecticide.
Summary of the invention
The objective of the invention is to the Radix Rhapontici seu Radix Echinopsis root is raw material, develops efficient, nuisanceless, vegetable insecticide-Radix Rhapontici seu Radix Echinopsis insecticide and manufacture method thereof cheaply.
Radix Rhapontici seu Radix Echinopsis insecticide of the present invention is cream pesticide or the microemulsion insecticide that contains the Radix Rhapontici seu Radix Echinopsis root extract.
When Radix Rhapontici seu Radix Echinopsis insecticide of the present invention is cream pesticide, it is characterized in that the extract of Radix Rhapontici seu Radix Echinopsis root and emulsifier, organic solvent are mixed with missible oil, the percentage by weight of each component is: Radix Rhapontici seu Radix Echinopsis root extract 8-55%, emulsifier 3-23%, organic solvent 30-75%.
Used emulsifier can be selected from one or more in many sorbitol esters, tween and the fatty alcohol-polyoxyethylene ether of nonionic; Perhaps be selected from NaLS, lauryl sodium sulfate and the N-methyl fatty acid amide taurate of anionic one or more.Used organic solvent can be selected from one or more in dimethylbenzene, ethanol, the ethyl acetate.
When Radix Rhapontici seu Radix Echinopsis insecticide of the present invention is microemulsion insecticide, the extract and emulsifier, cosolvent and the water that it is characterized in that the Radix Rhapontici seu Radix Echinopsis root are mixed with microemulsion, and the percentage by weight of each component is: Radix Rhapontici seu Radix Echinopsis root extract 5-60%, emulsifier 2-30%, cosolvent 1-20%, water 30-70%.
Used emulsifier can be selected from one or more in polyoxyethylene nonylphenol ether, phenethyl phenol polyethenoxy ether, polyoxyethylene glycol and the benzylphenol APEO of nonionic; Perhaps be selected from calcium dodecyl benzene sulfonate, neopelex and the alkyl diphenyl ether sulfonate of anionic one or more.Used cosolvent can be selected from one or more in isopropyl alcohol, acetone, ethylene glycol, n-butanol, linalool and the australene.
The used Radix Rhapontici seu Radix Echinopsis root extract of Radix Rhapontici seu Radix Echinopsis insecticide of the present invention can be made by following method: earlier Radix Rhapontici seu Radix Echinopsis root raw material being pulverized with the plant tissue cracker is the crushed material of 1-4.5mm, again with the solvent lixiviate of the crushed material of gained, leaching liquor becomes medicinal extract through vacuum concentration, 0.01-0.14g medicinal extract is equivalent to the 1g raw material, is required Radix Rhapontici seu Radix Echinopsis root extract; Solvent for use is any one or the multiple mixing in dimethylbenzene, ethanol, methyl alcohol, the ethyl acetate, and extracting temperature is 40-82 ℃, and extraction time is 5-23 hour.The ratio of lixiviate hourglass reed rhizome raw material and solvent generally can be 1: 1.2～1: 95 (w/v).
When Radix Rhapontici seu Radix Echinopsis insecticide of the present invention was cream pesticide, its preparation method was: Radix Rhapontici seu Radix Echinopsis root extract and emulsifier, organic solvent are controlled temperature in reactor be 40-60 ℃, stirred 30-40 minute, promptly can be made into the Radix Rhapontici seu Radix Echinopsis cream pesticide.
When Radix Rhapontici seu Radix Echinopsis insecticide of the present invention is microemulsion insecticide, its preparation method is: after earlier Radix Rhapontici seu Radix Echinopsis root extract and emulsifier, cosolvent being mixed in high-speed shearing machine, add deionized water again, mix, left standstill 2-8 hour, be heated to 46-58 ℃, after fully stirring, promptly can be made into the Radix Rhapontici seu Radix Echinopsis microemulsion insecticide.
Radix Rhapontici seu Radix Echinopsis insecticide of the present invention has following advantage:
1. the present invention is a kind of new and effective, vegetable insecticide that insecticidal action mechanism is special, and insects such as larvae, cabbage caterpillar and diamond-back moth are had remarkable drug effect.
2. insecticide of the present invention is to environment, people and animals, pest natural enemy and other beneficial organism safety, and insect is difficult for it is developed immunity to drugs.
3. insecticide bin stability of the present invention is good, can deposit more than 1 year.
4. insecticide of the present invention is with low cost, and manufacturing process is simple, is suitable for applying.
