Description
Technical field
The invention belongs to pesticides application technical field, and in particular to a kind of pesticide synergistic of leaf essential oil containing camphor tree and chlorfenapyr
Composition and its application.
Background technology
Camphor tree (Cinnamomum camphora) also known as cinnamomum camphora, black camphor tree, camphorwood, fragrant camphor tree etc., are that Lauraceae Cinnamomum is evergreen tall and big
Broad-leaved arbor.Camphor tree is one of China natural perfume material seeds, and the position such as its root, stem, leaf, fruit, which can be refined, isolates essence
Oil comes.The chemical composition of camphor tree essential oil is very abundant, the chemical composition for having about 300 kinds in camphor tree leaf essential oil.Camphor tree leaf essential oil
It is main into including the chemical combination such as linalool, safrole, camphor, borneol, nerolidol, different nerolidol, citral, geraniol
Thing；Most of chemical compositions play the role of sterilization, desinsection, antibacterial, in industries such as light industry, perfumery industry, beauty culture, pharmaceutical sectors
It is widely used, with wide exploitation prospect.
Chlorfenapyr, English name Chlorfenapyr, trade name eliminates suspending agent, Universal Chinese character name capillary.It is by U.S.
A kind of new type heterocycle class desinsection, mite killing, nematicide that cyanamide company of state succeeds in developing.As national high-toxic pesticide substitutes policy
Appearance and people's environmental consciousness raising, as non-polluted farm product insect pest preventing and controlling recommend pesticide species representative, low toxicity
The application of efficient chlorfenapyr is more and more extensive.
Chemical pesticide is used for a long time, causes Heavy environmental pollution, drug-fast increase, exploitation has desinsection wide spectrum, low toxicity,
The botanical pesticide for the advantages of being not likely to produce the resistance to the action of a drug and good Environmental compatibility is current hot subject.In addition by different structure
The pesticide active ingredient of type is compounded, and is current one kind the problems such as solve cost and resistance in agricultural chemicals single dose application process
Effective means.Compound synergic is formulated well, can improve actual prevention effect, is reduced the usage amount of agricultural chemicals, is helped to delay to resist
The generation of property, is the important means of scientific prevention and cure pest and disease damage.At home and abroad also compounded at present without camphor tree leaf essential oil with chlorfenapyr
Relevant report.
The content of the invention
It is an object of the invention to provide a kind of plant pesticide composition with notable synergistic effect, with low toxicity, environment
Friendly the characteristics of.
It is another object of the present invention to provide a kind of new application for synergistic composition.
To overcome the deficiencies in the prior art, inventor is tested by a large amount of indoor bioassay, has been surprisingly found that camphor tree folic acid
After oil and chlorfenapyr are compounded with certain proportion, significant synergistic effect is respectively provided with to diamondback moth, tea geometrid.
The pesticide synergistic composition of the present invention includes active components A and active component B, and active components A is camphor tree leaf essential oil,
Active component B is chlorfenapyr, and active components A and active component B weight ratio are 1:30-30:1.
Further, active components A and active component B weight ratio are 1 in described pesticide synergistic composition:10-15:
1。
Present invention also offers a kind of pesticidal preparations for including described pesticide synergistic composition, also comprising can agriculturally connect
The auxiliary agent received.
Preferably, in described pesticidal preparations, active components A and active component B weight percentage are 0.1-
40%.
Preferably, the formulation of described pesticidal preparations is missible oil, suspending agent, wettable powder, water dispersible granules, water and milk
Agent or microemulsion.
It is used for the purposes for preventing and treating crop pest present invention also offers described pesticidal preparations.
It is used for the purposes for preventing and treating diamondback moth, tea geometrid present invention also offers described pesticidal preparations.
The extracting method of camphor tree leaf essential oil of the present invention：First collection camphor tree blade (tender leaf, old leaf or it is fresh fall
Leaf), after cleaning, leaf surface moisture is dried naturally, it is stand-by；Next weighs a certain amount of material handled well, shreds and is put into round bottom burning
In bottle, extracted in volatile oil extractor with steam distillation, distillation time 4h, essential oil anhydrous Na2SO4Dry, obtain
The sealing of camphor tree leaf essential oil is stand-by.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) pesticide synergistic composition of the invention has obvious synergistic effect, reduces dosage, can effectively prevent and treat pair
Existing medicament has produced the insect of resistance.
(2) dispenser of pesticide synergistic composition of the invention simultaneous can control various pests, reduce drug cost.
(3) pesticide synergistic composition of the invention is by mixture, and action site increase is conducive to overcoming and delays insect to produce
The raw resistance to the action of a drug, extends the service life of medicament.
(4) active component of pesticide synergistic composition of the invention is botanical pesticide, with low toxicity, is not likely to produce anti-
The advantages of property of medicine and good Environmental compatibility.
Embodiment
The present invention is described in detail its advantage with specific examples below.
First, indoor virulence test is determined
Biologicall test example 1：Camphor tree leaf essential oil and chlorfenapyr pesticide synergistic composition are to tea geometrid Toxicity Determination
Subjects：Tea geometrid
Method of testing is leaf dipping method.Transplant and dry after fresh tea blade tip is impregnated in decoction, cut the tea tip dried and put
Enter in can, every bottle of 3-4 tea tip, select in 2 instar larvae access can of the same size, each processing connects worm 15,
In triplicate, 26-27 DEG C of temperature control, and suitable humidity is kept, feed fresh normal blade.120h investigates its death after medicine
Rate, concentration LC50 in suppressing is calculated with least square method, then calculate co-toxicity coefficient (CTC) according to the abundant methods of Sun Yun.
As CTC ＜ 80, then composition shows as antagonism, as 80 ＜ CTC ＜ 120, then composition shows as being added and made
With as CTC ＞ 120, then composition shows as synergistic effect.
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50) × 100
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100；Poison
Power measurement result is as shown in table 1.
The camphor tree leaf essential oil of table 1 and chlorfenapyr synergistic composition are to tea geometrid indoor virulence
As shown in Table 1, in insecticidal synergistic composition of the invention camphor tree leaf essential oil and chlorfenapyr in specific ratio range,
Said composition has notable synergistic effect to tea tree tea geometrid；When the quality proportioning of camphor tree leaf essential oil and chlorfenapyr is 1:30-30:
In the range of 1, its co-toxicity coefficient is all higher than 120, shows notable synergistic effect；Especially when the matter of camphor tree leaf essential oil and chlorfenapyr
Amount proportioning is 5:When 1, its co-toxicity coefficient is 181.95, shows very strong synergistic effect.
Pesticidal combination of the present invention can be prepared into the preparation for being adapted to agriculturally use with known method.It is as described below only
