Abstract
The present invention relates to a kind of composition pesticide for being used to prevent and treat root-knot nematode, active component is iprodione and sulfoxaflor, iprodione and sulfoxaflor combination have synergistic effect to root-knot nematode, improve prevention effect, delay root-knot nematode to produce iprodione, sulfoxaflor resistance.
Description
Technical field
The invention belongs to composition pesticide technical field, is related to active ingredient iprodione and is combined with sulfoxaflor for preventing
Root-knot nematode is controlled, improves actual prevention effect.
Background technology
Root-knot nematode (Meloidogyne) is a kind of omnivorousness pathogenic root-knot nematode of height specialized form.Root knot line
Worm is mainly caused harm the roots of various vegetables, shows as lateral root and fibrous root more normally increases, and is formed on the fibrous root of young root spherical
Or the white root nodule that cone differs in size, some is in beads shape.Killed strain overground part growth is short and small, slow, leaf color is abnormal, knot
Fruit is few, yields poorly, or even causes plant to do sth. in advance death.Root-knot nematode can also trigger fungi and bacterial disease, such as droop, sudden
The root disease such as disease, root rot, soft rot.
Iprodione is dicarboximide class high-efficiency broad spectrum, contact killing type bactericide.Sulfoxaflor is sulfoximide insecticide, is made
For the nervous system of insect, that is, act on binding site unique in nicotinoids acetylcholinergic receptor (nAChR) and play and kill
Worm function.
Target organismses determination of activity and different cultivars are combined by compound, is exploitation agricultural chemicals, improves prevention effect, prolongs
Delay one of effective ways of disease, worm, crop smothering resistance.The present inventor is goed deep into iprodione, sulfoxaflor and combinations thereof
Research, it is found that iprodione, sulfoxaflor have preferably activity to root-knot nematode, iprodione and sulfoxaflor carry out mixture,
There is obvious synergistic effect to root-knot nematode in certain mixed ratio scope, preventing and treating root-knot nematode effect can be effectively improved.Through
Further research, completes the present invention.
Iprodione and sulfoxaflor mixture there is no report at present for preventing and treating root-knot nematode.
The content of the invention
It is an object of the invention to provide it is a kind of there is greater activity to root-knot nematode contain iprodione and flonicamid
The composition pesticide of nitrile, actual prevention effect is improved, effectively delays root knot nematode resistance to produce.
Technical solution of the present invention：A kind of composition pesticide for being used to prevent and treat root-knot nematode, active ingredient is iprodione and fluorine
The ratio of weight and number of sulfoxaflor, iprodione and sulfoxaflor is 20：1~1：20, iprodione and sulfoxaflor weight are total
Percentage by weight in the composition is 0.01%~30%, and remaining is auxiliary agent.

The present composition is used to prevent and treat crops root-knot nematodes, especially tomato root-knot eelworm.
Present composition occupation mode is to spread fertilizer over the fields or pour, and frequency of use and usage amount are with weather conditions and root-knot nematode
Situation of the harm changes and changed, and the purpose of preventing and treating can be reached by using appropriate dosage.
Compared with prior art, the advantage of the invention is that：1st, after iprodione and sulfoxaflor mixture, have obvious
Synergistic effect, improve prevention effect.2nd, after iprodione and sulfoxaflor mixture, single use can be overcome easily to produce anti-
Property the shortcomings that, delay the drug-fast generation of pest and disease damage, extend medicament service life.3rd, after iprodione and sulfoxaflor mixture,
Drug effect greatly improves, and reduces Pesticide use amount, reduces drug cost, reduces infringement and dirt of the agricultural chemicals to ecological environment
Dye.
Embodiment
Essence for a better understanding of the present invention, present disclosure is described in further detail with reference to embodiment,
Content mentioned in embodiment is not limitation of the invention, and the selection of the process conditions such as temperature, time can in preparation method
Suit measures to local conditions and substantial effect is had no to result.
Embodiment 1：Iprodione, sulfoxaflor and its mixture are tested the indoor biometricses of tomato root-knot eelworm.
Test method：The Tomato Root System seriously caused harm is taken, running water is gently rinsed well, and gently picking is sick with dissecting needle
Milky egg capsule on root, is put into diameter 6cm small culture dish, adds a small amount of sterilized water, in 25 DEG C of insulating boxs hatch 3~
4d, collect 2 instar larvaes, and add sterilized water be configured to finite concentration (500/milliliter or so) suspension it is standby.
5 concentration gradient processing of setting, using sterilized water as blank control.96 porocyte culture plates are taken, adds and prepares per hole
Various concentrations 150 microlitres of medicament, add isometric root-knot nematode suspension, moisturizing culture under the conditions of 25 DEG C, respectively
Different time after treatment checks the amount of survival and The dead quantity of the instar of root-knot nematode 2, and root-knot nematode motionless is in stiff
Dead worm, root-knot nematode are worm living in bending wriggling state.Calculate the death rate and corrected mortality.
According to survey data, the corrected mortality of each processing is calculated.And use the abundant methods of Sun Yun with reference to NY/T1154.1-2006
Calculate the co-toxicity coefficient (CTC values) of mixture.If compareing death rate ＜ 5%, do not correct；The death rate is compareed between 5%-20%,
It is corrected；Death rate ＞ 20% is compareed, experiment need to reform.Using the logarithm value of drug concentration (mg/L) as independent variable x, with correction
The probit value of the death rate is dependent variable y, establishes virulence regression equation respectively, calculates single dose using DPS softwares and each proportioning is mixed
The LC of agent50、LC90And its mixture co-toxicity coefficient, compare synergy situation.Acted on according to NY/T11547.7-2006 insecticide combinations
The criteria for classifying：Co-toxicity coefficient (CTC values) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC values)≤120 shows as antagonism work
With；80 ＜ co-toxicity coefficients (CTC values) ＜ 80 shows as summation action.
Measurement result shows that iprodione and sulfoxaflor compounding match 20:1、10:1、1:1、1:10、1:20 pairs of root knots
Nematode co-toxicity coefficient (CTC values) >=120, it is synergistic effect to root-knot nematode to illustrate iprodione and sulfoxaflor mixture.
The bioassay results of table 1, iprodione, sulfoxaflor and its mixture to root-knot nematode.
Embodiment 2：2% iprodione sulfoxaflor granule.
Above-mentioned material is well mixed in closed compounding kettle, coating method is granulated, and is dried under the conditions of 120 DEG C to particle
Water content 1%, screening, 2000 microns of particle size range (μm), through after the assay was approved, that is, obtaining 2% iprodione sulfoxaflor
Granule.
Embodiment 3：20% iprodione sulfoxaflor suspending agent.
Above-mentioned material is crushed in advance in proportion, adds in sand mill and grinds, system is allocated after high shear mixing
Obtain 20% iprodione sulfoxaflor suspending agent.
Embodiment 4：Prevent and treat the tomato root-knot eelworm test of pesticide effectiveness.
Test medicine：(1) 20% iprodione sulfoxaflor suspending agent (15% iprodione:5% sulfoxaflor),
(2) 225 g/l of iprodione suspending agents (comparison medicament 1), (3) 50% sulfoxaflor water dispersible granules (comparison medicament 2)
Use age：7 days after tomato transplanting
Application method：It is watered pouring root
Result of the test：2 are shown in Table, as can be seen from the test results：30 days after dispenser, 50 days, composition pesticide of the invention
20% iprodione sulfoxaflor suspending agent dissipates significantly better than 225 g/l of iprodione suspending agents, 50% sulfoxaflor moisture
Granula single dose, illustrate that the present invention improves actual prevention effect, reduce dosage, effectively administer the anti-generation of root-knot nematode.
Table 2, the field control effectiveness test result for preventing and treating tomato root-knot eelworm.
