Abstract
The present invention relates to a kind of for preventing and treating the granule of carrot root-knot nematode, and effective component is by following weight ratio at being grouped as: Tea Saponin 2-5%, fosthiazate 2-10%, wherein the weight ratio of Tea Saponin and fosthiazate is 1-3:1-5.Two active constituent synergy of the invention, mixture can be reduced the amount of application of each single dose, advantageously reduce pesticide cost, while being conducive to that root knot nematode resistance is delayed to develop.
Description
Technical field
The present invention relates to agricultural technology fields, and in particular to a kind of for preventing and treating the granule of carrot root-knot nematode.
Background technique
Root knot nematode disease is one of carrot Major Diseases, especially serious in the morbidity of carrot many years continuous cropping production district, continuously
Plantation 3 years or more carrot fields, root knot nematode disease morbidity less serious case lead to underproduction 15-30%, and the severe one underproduction is up to 50% or more, sternly
The yield and quality of carrot is affected again.
Carrot Roots Root-knot endangers carrot subterraneous root, and field Symptoms are fleshy root branch into finger-shaped, radicula
It grows thickly to form fibrous root group, fibrous root group, which goes up, gives birth to the root knot that calabash shaped is irregularly arranged, interior visible white or yellow-white shot-like particle.Ground
Top performance symptom is different because of occurring degree difference, and when falling ill light, only partial blade turns to be yellow overground part diseased plant, without other obvious diseases
Shape；When severe disease, overground part vine growth and development is bad, plant is downgraded, blade is thin and weak, it is withered ahead of time to cause plant.
Tea Saponin, English common name: tea saporin, is a kind of botanical pesticide, and Tea Saponin is applied to the prevention and treatment of nematode
In had relevant report, as " it is living that the identification of Anhui Province's plant root-knot nematode and Tea Saponin kill line to Meloidogyne incognita to paper
Journal of Sex Research " in point out, Tea Saponin can inhibit infecting for nematode, have nematicide activity, while to plant height, ground fresh weight, root
With increasing action.
Fosthiazate, chemical name are as follows: O- ethyl-S- sec-butyl -2- oxo -1,3-thiazoles alkane -3- base Thiophosphonate is
A kind of organic phosphates nematicide has and tags and stomach poison function, and crop root kill is drawn in energy and has invaded crop root shape
At the root-knot nematode of root nodule.
Fosthiazate is the main pesticide control of current nematode, but due to long-term continuous single use, causes root-knot nematode
Resistance increases, and preventive effect reduces.It is that pre- preventing disease and pest resistance aggravates common do with the farm chemical ingredients mixture of different role mechanism
Method, by mixed pesticide, synergy is significantly formulated the amount of application that can be reduced each single dose, helps to reduce pesticide cost, and have
Conducive to the development for delaying pest and disease damage resistance.
Currently, using Tea Saponin, fosthiazate as the composition of main active mixture, for the anti-of carrot root-knot nematode
There are no relevant reports in controlling.
Summary of the invention
The object of the present invention is to provide a kind of for preventing and treating the granule of carrot root-knot nematode, has synergy, reduces
Applications of pesticide amount and the advantages of delaying nematode resistance.
The technical solution used in the present invention is: a kind of for preventing and treating the granule of carrot root-knot nematode, effective component by
Tea Saponin and fosthiazate composition, weight percent of the Tea Saponin in granule are 2-5%, weight of the fosthiazate in granule
Percentage is 2-10%.
Weight ratio of the Tea Saponin and fosthiazate in granule is 1-3:1-5, preferred Tea Saponin and fosthiazate
Weight ratio be 1:2.
The adjuvant that the granule uses include filler, binder, dispersing agent, colorant, disintegrating agent, sustained release agent or
It is other to be beneficial to the active constituent stable substance played with drug effect in the formulation, it is all to commonly use in agriculture field preparation or allow to make
Various composition.
Compared with prior art, the beneficial effect that the present invention has is:
(1) Tea Saponin is different with fosthiazate mechanism of action, and the two mixture is synergistic, can be reduced the amount of application of each single dose,
Pesticide cost is reduced, while being conducive to delay the development of root knot nematode resistance.
(2) active constituent Tea Saponin of the invention can promote the growth of crop while can control eelworm harm, to recklessly
The ground fresh weight of radish, root long have increasing action；And Tea Saponin is medicine based on herbs, can reduce the use of chemical agent, is reduced
Pesticide residue toxicity.
Specific embodiment
Technical solution of the present invention and beneficial effect are described further with reference to embodiments, of the present invention hundred
Ratio is divided to be weight percentage.
One, indoor joint toxicity measuring test
5 concentration are diluted by active constituent content gradient series with Tea Saponin, fosthiazate and its mixed agent.Test is with south
2 instar larvae of root-knot nematode is test worm, and blank control is arranged, and Tea Saponin, fosthiazate and mixture are carried out virulence survey using dip method
Determine and statistically analyze, the synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient method (CTC), is i.e. CTC≤80 are antagonism work
With 80 ﹤ CTC ﹤ 120 are summation action, and CTC >=120 are synergistic effect.Final statistical result is as shown in table 1:
The indoor toxicity test of 1 Tea Saponin of table, fosthiazate and its mixed agent to 2 instar larvae of Meloidogyne incognita
As seen from the above table, when weight ratio is 1-3:1-5 mixture, co-toxicity coefficient (CTC) is all larger than for Tea Saponin and fosthiazate
120, show synergistic effect, when wherein the weight ratio of Tea Saponin and fosthiazate is 1:2, co-toxicity coefficient is maximum, and synergy is the most significant.
