Description
Technical field
The invention belongs to technical field of pesticide, specifically disclose a kind of nematicidal composition containing Benfuracard micro.
Technical background
Benfuracard micro is efficient (benfuracarb), wide spectrum carbamate insecticides, by inhibiting cholinesterase
Keep pest lethal.With tag, stomach toxicity and systemic action, based on stomach toxicity.Suitable for rice, corn, beet, potato, cotton
The crops such as flower, fruit tree prevent and treat various pests and the nematodes such as snout moth's larva, brown paddy plant hopper, cotten aphid.In addition, long there are also the lasting period, anti-to generating
Property pest has the characteristics of preventive effect.
102696609 B of CN discloses the compound of formula (I), and specification [0027]-[0029] section discloses formula (I)
The structural formula and synthetic method of compound, specification [0016] section disclose its activity to tomato root-knot eelworm.
Plant nematode is a kind of very harmful pathogenic microorganism, has a very wide distribution, is many kinds of, environment adapts to
Ability is strong, can colonize in root system, stem, leaf, seed, young shoot and the fruit of plant, can be by feeding activity to host plant
Mechanical damage is caused, and robs the nutrition of host plant, especially its esophageal gland secretion will lead to one system of host plant generation
Epidemy becomes, and can also infect jointly host plant with other pathogenic microorganisms, cause compound disease, cause production loss.In the whole world
In range, agricultural losses caused by plant nematode is annual are up to 100,000,000,000 dollars or more, seriously constrain agricultural economy
Development.
Application chemical agent is one of most effective chemical means of prevention and treatment plant pathogeny line insect disease；With not cross resistance
Novel pesticide is come to prevent and treat plant pathogeny line insect disease be a good solution；But it is public according to Phillips McDougall
The research of department, compared to 2005-2008 years, between 2010-2014 years, 1 pesticide activity component was developed and is registered in discovery
30,000,000 dollars of increased costs are averagely researched and developed, 11.7% are increased in other words, up to 2.86 hundred million dollars.And in 2005-2008 years
Between, the average unit cost of agricultural chemicals research and development is 2.56 hundred million dollars, increases 39% compared with 2000；Average research and development cost in 2000 is
1.84 hundred million dollars, 21% is increased compared with nineteen ninety-five, while the development cycle is 5-10, is difficult the upper plant pathogeny line insect caught up with generation
The speed of drug resistance；Other methods such as crop structure adjustment, different pesticide rotations etc., in the actual operation process, have been difficult
To apparent effect.
Exploitation new product pesticide price is expensive, the period is long, and in contrast, it develops and studies efficient, less toxic, low-residual answer
And have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The combination of Benfuracard micro and formula (I) compound has not been reported.
Summary of the invention
The invention belongs to technical field of compounded pesticide, provide a kind of synergetic pesticide composition that effective component is A and B,
Middle A is selected from Benfuracard micro, and it be the prevention and control of crop nematodiasis is especially that crop root knot nematode disease mentions that B, which is selected from formula (I) compound,
For a kind of effective management tool.
The invention is realized by the following technical scheme:
The present invention relates to a kind of synergistic compositions containing Benfuracard micro compounding, and containing active components A and B, A is selected from third
Carbosulfan, B are selected from formula (I) compound, and formula (I) structural formula of compound is as follows:
The weight part ratio of A and B is 1:3~1:6, and further preferred ratio is 1:3,1:4,1:5,1:6.
The composition effective component total content is 0.1%~60%；The weight of further preferably active component is group
The 5%~30% of object total weight is closed, remaining is insecticides adjuvant.
The composition is added auxiliary agent and excipients and granule, suspending agent etc. is made agriculturally by certain technological means
Common dosage form.
The granule dosage form weight percent composition are as follows: active components A 0.1~20%, active constituent B0.1~
40%, dispersing agent 0.1~3%, disintegrating agent 1~12%, wetting agent 0.1~3%, binder 0.1~12%, solid carrier are supplied
To 100%.Specific production stage are as follows: specific production stage are as follows: be uniformly mixed active constituent and other auxiliary agents, through mediating, so
It is added in fluidized-bed granulation dryer afterwards and is granulated, dries, sieve, the granule of corresponding weight percentage is made；A is selected from
Benfuracard micro, B are selected from formula (I) compound.
The wetting agent can be lauryl sodium sulfate, neopelex, sodium butylnaphthalenesulfonate, alkyl sulphur
One or more of sour sodium, tea seed cake powder, spaonin powder, spaonin powder, cornstarch, sorghum starch, buckwheat etc..
The dispersing agent can be APES formaldehyde condensation product, naphthalenesulfonate formaldehyde condensation compound, to first

The beneficial effects of the present invention are:
Formula (I) compound and Benfuracard micro have synergistic effect to plant pathogeny line insect.
Specific embodiment
It is raw to survey embodiment
According to Sun Yunpei's Method, the synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient (CTC), i.e. CTC≤80 are association
Same antagonism, 80 < CTC < 120 are joint action of antagonism, and CTC >=120 are synergistic function.Survey toxicity index
(ATI)=(LC of standard agent50The LC of/reagent agent50)×100；
The virulence of the percentage composition+B medicament of A medicament refers in toxicity index × mixture of theoretical toxicity index TTI=A medicament
The percentage composition of B medicament in number × mixture；
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
Formula (I) compound Benfuracard micro is to Meloidogyne incognita (Meloidogyne incongnita
Chitwood indoor toxicity test), subjects are picked up from the Cucumber root-knot nematode disease insect gall in field using the graceful funnel method of shellfish
The Meloidogyne incognita (Meloidogyne incongnita Chitwood) separated.
Using the The Toxicity Determination result and the two different proportion of tag method measurement formula (I) compound, Benfuracard micro
Combination the prepared medical fluid of various concentration is pressed to the indoor biological activity of test worm.The nematode of 0.5ml medical fluid and 0.5ml are suspended
Liquid is added in 24 well culture plates.Each processing is repeated 3 times.24 orifice plates are obturaged with sealed membrane and are placed on 48h in 25 DEG C of incubators, so
Each processing and control nematode suspension are poured into 500 meshes and filter off medical fluid afterwards, with aseptic water washing and recycles nematode in culture
In ware, rear microscopy nematode death condition, calculates corrected mortality, acquires virulence regression equation and calculate LC for 24 hours50Value.
Table 1: formula (I) compound Benfuracard micro is to Meloidogyne incognita (Meloidogyne incongnita
Chitwood The Toxicity Determination result (activity of second instar larvae)).
As shown in Table 1, formula (I) compound and Benfuracard micro mixture are between 6:1~2:1, to Meloidogyne incognita
(Meloidogyne incongnita Chitwood) has synergistic effect, and co-toxicity coefficient is 120 or more；Formula (I) compound
With Benfuracard micro between 30:1-7:1 and 1:1-1:15 is to Meloidogyne incognita (Meloidogyne incongnita
Chitwood) there is no synergistic effect.
