Abstract
The invention discloses a compounded botanical synergistic pesticide. The obtained compounded botanical synergistic pesticide takes sophocarpidine and macleaya alkaloids as main components, and is added with accessory ingredients in a synergistic manner; the morphology of the compounded botanical synergistic pesticide is environment-friendly missible oil, water aqua or soluble liquid; and in addition, the compounded botanical synergistic pesticide comprises sophocarpidine accounting for 0.1 to 20 percent and the macleaya alkaloids accounting for 0.1 to 20 percent, and the rest is the accessory ingredients. The compounded botanical synergistic pesticide is mainly used for controlling aphides on melons, fruits and vegetables as well as agricultural pests such as red spiders, Chinese chive maggot, poratrioza sinica yang et li, psylla chinensis, imported cabbageworm, cabbage moths and army worms. The compounded botanical synergistic pesticide does not contain any chemical pesticide component, is easy to degrade in environment, has no consideration of environment pollution and residual hazard, is safe to human, livestock and environment; pests are not easy to be drug-resistant to the compounded botanical synergistic pesticide; the compounded botanical synergistic pesticide is of great value to be applied and popularized on main agricultural and sideline products that earn foreign exchange through exports, such as the melons, the fruits, the vegetables, flowers and medicinal materials; and in addition, the compounded botanical synergistic pesticide is an ideal novel pollution-free pesticide.
Description
Technical field
The invention belongs to technical field of pesticide; Be specifically a kind of be insecticide of active component and preparation method thereof with matrine and Macleaya cordata alkaloids two plant species source materials, be mainly used in the control melon, really, pest such as the aphid on the vegetables, two spotted spider mite, fragrant-flowered garlic maggot, matrimony vine wood louse, pear sucker, cabbage caterpillar, diamond-back moth, mythimna separata.
Background technology
Aphid, two spotted spider mite, fragrant-flowered garlic maggot, matrimony vine wood louse, pear sucker, cabbage caterpillar, diamond-back moth, mythimna separata etc. be melon, really, the primary pest on the vegetables, flowers, damaging range is wide, difficulty is bigger in control.The medicament of these insects of control mainly is a chemical agent at present, yet long-term a large amount of chemical medication has caused producing the appearance of problems such as pesticide resistance, environmental pollution, harm humans health; In addition, the export of farm produce suffers the impact of " green barrier " repeatly, causes country to have to limit the use of many chemical pesticides.From the natural resources treasure-house, seek insecticide active substance, becoming the important channel and research focus of novel pesticide initiative.Particularly the science through multiple components composite after, the effect of vegetable source pesticide active substance can significantly improve.
Matrine is to extract a kind of water-soluble alkaloid that obtains by root, stem and the fruit of pulse family Sophora machaka kuh-seng (SophoraflavescensAit) through strict process, and outward appearance is the brown homogeneous liquid.Be generally Banlangen, its main component has matrine, oxymatrine, sophocarpine, N-Oxysophocarpine, Sophoridine etc.Wherein the content with matrine and oxymatrine is the highest.
Matrine is the broad spectrum activity plant insecticide, and insect is had stomach toxicity and action of contace poison.Mainly act on the nervous system of insect, the sodium-ion channel of insect nerve cell is had the concentration dependent blocking effect, can cause the nervous centralis paralysis, and then suppress the respiration of insect, make insect death by suffocation.Can effectively prevent and treat Lepidoptera, Homoptera, coleoptera, acarina pest such as aphid class, stinkbug class, cabbage caterpillar, diamond-back moth, peach fruit borer, rice fulgorid, rice leaf roller, two spotted spider mite etc.
Macleaya cordata alkaloids is the main active of Papaveraceae Macleaya plant macleaya cordata, and it contains multiple single alkali such as sanguinarine, dihydrosanguinarine and dish alkali in the wrong.Wherein sanguinarine mainly is present in the herb of greater celandine, the piece root of corydalis, the herb of macleaya cordata, the acrial part of snowpoppy.Evidences such as Sun Guangzhong, 1% sanguinarine wetting powder has good insect killing effect to the apple Tetranychus urticae, and working concentration is in the time of 2500 times, and 2500 times of liquid phases of 20% pyridaben wetting powder of promoting the use of in control efficiency and the production are worked as; Dihydrosanguinarine has higher toxic action to mythimna separata 3 instar larvaes; The macleaya cordata that makes with the acidic ethanol extraction method is to being tried the LC of suede tail fly maggot maggot in 3 age
50Be 148.75g/L, 95% credibility interval is 122.19g/L-180.94g/L.
According to the data-searching that the applicant did; At present the sanguinarine of one of main component is composite or mainly contain with matrine, the composite mixed insecticide that is the basis of sanguinarine in matrine and the macleaya cordata extracts: Wang Zhengguo etc. have applied for the patent of jamaicin matrine sterilization and disinsection aqua; Publication number is CN1401235, and this invention mainly contains jamaicin 0.5%～2.5% and matrine 0.1～2.0%.The present invention is mainly used in insects such as preventing and treating mythimna separata and kill bacteria etc.Lv Shilu has applied for the patent of 0.36% matrine water agriculture chemicals and production method thereof; Publication number is CN1422531, it is characterized in that vegetable insecticide processed by kuh-seng, the tuber of stemona, tobacco, China tree, Dalmatian chrysanthemum compatibility, and its compatibility is: kuh-seng: 52.5～72kg;

3, supply to study thing
Matrimony vine
4, experimental scheme and method
The cultivation condition of testing all sub-districts comprises that land type, cultivation management, matrimony vine kind and upgrowth situation etc. are all consistent.Matrimony vine wood louse 2-3 contains the phase in age at a time when the test, and with supplying 500,1000,1500 times of liquid measures of reagent agent to carry out the blade face conventional spray, 3000 times of liquid of 4.5% efficient cyhalothrin emulsifiable concentrate carry out the blade face conventional spray for the contrast medicament, and establish the clear water contrast.3 repetitions, every repetition area 20m are established in test
2, randomized arrangement.5 orientation of every strain investigation, each orientation adopts five point samplings, 5 blades of random searching write down and calculate per 100 blade ovum amounts, respectively at before the spray medicine with the spray medicine after 3d, 7d, 10d investigate, and the statistics ovum number of living calculates control efficiency.Computing formula is with checking embodiment 1.Test of pesticide effectiveness result is as shown in table 6:
Table 6 nine plant species insecticides are to the field control effectiveness test result of matrimony vine wood louse
Can find out by last table; Under 500 times of 9 medicine based on herbs, preventive effect is all more than 70%, after 3 days after 1 day; Pharmacy control efficacy rises to more than 85%, and KXS-1, KXS-2, KXK-1, KXR-1 reach 93.49%, 92.54%, 92.71% and 95.13% respectively after 7 days; Under 1000 times of processing, the preventive effect of 9 medicaments in the time of 3 days is all more than 76%, and the preventive effect in the time of 7 days is all more than 82%, and it is more obvious that the slow characteristic of plant resource material shows.In general, the control efficiency with medicament KXS-1, KXS-2, KXK-1, KXR-1 is good than other medicaments in 9 medicine based on herbs.
The field experiment result of comprehensive above three tables, nine plant species insecticides have all shown slow property in field trial, and quick-acting is not as chemical agent.Analyze reason, this possibly be that the essence of effect is just because of results of interaction between the multiple composition by the complicated constituent decision of active substance of plant.In addition, plant insecticide has certain lasting period (7～9 days), and to non-target organism and environmental friendliness, therefore very suitable in economic crops and organic food exploitation.
