Abstract
The invention relates to nematicide containing benfuracarb and amino-oligosaccharin. The nematicide disclosed by the invention comprises the benfuracarb, the amino-oligosaccharin, auxiliary and excipient; the weight ratio of the benfuracarb to the amino-oligosaccharin is 10:1 to 1:2. Compared with the prior art, the nematicide disclosed by the invention is capable of thoroughly preventing and curing root-knot nematode in the whole growth period of crops; the preventive effect is high; the invest cost per mu is low; the amino-oligosaccharin and the benfuracarb are used in a mixed manner; the synergistic effect is obvious; furthermore, the nematicide disclosed by the invention is capable of increasing resistance of crops to a variety of diseases, such as root-knot nematode, viroses of plant, wilt, epidemic diseases and the like.
Description
Technical field
The present invention relates to the Techniques For Chemical Control field of root-knot nematode, specifically a kind of nematocide containing Benfuracard micro and amino-oligosaccharide.
Background technology
At present, for the control of root-knot nematode, chemical prevention and control method remains most convenient prophylactico-therapeutic measures efficiently and effectively, due to residual contamination malicious to height and to environment, a series of high-toxic pesticides such as carbofuran, Aldicarb, Isofenphos methyl, phonamiphos, isazofos, fenamiphos are disabled on the crops such as vegetables, fruit, tealeaves.At present, there is following problem in the chemical agent of control root-knot nematode: (1) residue of pesticide are high, and (2) input cost is high, and (3) preventive effect is remarkable not, and (4) have much room for improvement to the yield and quality of crop.
Summary of the invention
Technical problem to be solved by this invention is the defect existing for above-mentioned prior art, a kind of nematocide containing Benfuracard micro and amino-oligosaccharide is provided, reduce agricultural chemicals doing residual in object, significantly improve the preventive effect to root-knot nematode, reduce a mu input cost.
The present invention solves the problems of the technologies described above taked technical scheme: a kind of nematocide containing Benfuracard micro and amino-oligosaccharide, comprise Benfuracard micro, amino-oligosaccharide, auxiliary agent and excipient, the weight ratio of Benfuracard micro and amino-oligosaccharide is 10:1-1:2.
Compared with prior art, the beneficial effect that the present invention possesses is:
(1) can thoroughly prevent and treat the root-knot nematode of whole crop growth period, preventive effect is high;
(2) mu input cost is low;
(3) amino-oligosaccharide is mixed to use with Benfuracard micro, synergistic effect is obvious.Amino-oligosaccharide can also inducing plant resistance, promote plant POD, the active raising of SOD, PAL, promote the synthetic protective plant protecting agent of plant, excite the synthetic and accumulation of plant lignin, improve crop resistance, Promoting plant growth, and the multiple diseases such as the viroses of plant, fusarium wilt, epidemic disease are all had to good preventive effect.
Embodiment
By the following examples technical scheme of the present invention and beneficial effect are described further.
One, indoor joint toxicity measuring test
The indoor joint toxicity measuring test of Benfuracard micro and amino-oligosaccharide mixture, with the single dose medicament in contrast of Benfuracard micro, amino-oligosaccharide, and prepare No. 1-mixture of mixture No. 8 according to following ratio:
No. 1, mixture: Benfuracard micro: amino-oligosaccharide=12:1
No. 2, mixture: Benfuracard micro: amino-oligosaccharide=10:1
No. 3, mixture: Benfuracard micro: amino-oligosaccharide=8:1
No. 4, mixture: Benfuracard micro: amino-oligosaccharide=5:1
No. 5, mixture: Benfuracard micro: amino-oligosaccharide=2:1
No. 6, mixture: Benfuracard micro: amino-oligosaccharide=1:1
No. 7, mixture: Benfuracard micro: amino-oligosaccharide=1:2
No. 8, mixture: Benfuracard micro: amino-oligosaccharide=1:4
Test, take Meloidogyne incognita second instar larvae as examination worm, arranges blank, and Benfuracard micro, amino-oligosaccharide single dose and above-mentioned 8 mixtures are adopted to dip method, carries out toxicity test and does statistical analysis, and final statistics is as shown in the table:
The measurement result of indoor joint toxicity measuring test shows, except the co-toxicity coefficient of No. 8, No. 1, mixture and mixture is less than 120, shows that beyond summation action, the co-toxicity coefficient that No. 7, No. 2-mixture of mixture is all greater than 120, and synergistic effect is obvious.
