Abstract
The present invention relates to a kind of composition pesticide that root-knot nematode diseased plant delays seedling fast that can promote, active ingredient is made up of lythidathion, amino-oligosaccharide and humus, and the weight ratio of lythidathion, amino-oligosaccharide and humus is 5-10:1:5-10.Synergistic effect of the present invention is obvious, and promote that diseased plant takes root slow seedling, namely the plant be injured grew new root in 10-15 days, and the lasting period reaches more than 2 months.
Description
Technical field
The present invention relates to a kind of nematicide agricultural technology field, be specifically related to a kind of composition pesticide that root-knot nematode diseased plant delays seedling fast that can promote.
Background technology
The pathogenic of root-knot nematode is mainly manifested in two aspects, one is invade from plant root tip meristematic tissue with second instar larvae, secreted by esophagus after intrusion and form a kind of enzyme and plant hormone, stimulate host cell division, form megabacterium, and then form root knot, very large injury is caused to the conducting system of root, have impact on the normal transport of moisture and nutrient, cause overground part can not normal growth.Two is that second instar larvae invades the wound formed, and is conducive to the intrusion of other pathogens, thus causes the generation of other diseases such as fusarium wilt, damping off
After root-knot nematode is infected, the conducting tissue of plant is subject to grievous injury, have impact on the transport of root tissue water status and nutrient, and then have impact on the growth of overground part.Therefore, after plant is infected, plant height, stem are thick, overground part fresh weight, root system fresh weight and output all obviously reduce.Based on the requirement of economic benefit, peasant household is especially concerned about makes diseased plant slow seedling fast while control root-knot nematode.
At present, on market and be no lack of control root-knot nematode effective agent, effect is preferably as Avermectin, lythidathion and Benfuracard micro etc., these medicaments are for root-knot nematode Be very effective, substantially root-knot nematode can be killed after general 20 days, crop is made to grow new root, but often after one and a half months, root-knot nematode starts wildness again, need continuous use, cost of labor and drug cost high, and similar one month of the diseased plant that is injured just slow seedling gradually, just slow seedling is caused harm again, for the prevention of root-knot nematode or lasting period and slow seedling effect all not ideal enough.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of composition pesticide that root-knot nematode diseased plant delays seedling fast that can promote.
The present invention solves the problems of the technologies described above taked technical scheme: a kind of composition pesticide that can promote root-knot nematode diseased plant slow seedling fast, active ingredient is made up of lythidathion, amino-oligosaccharide and humus, and the weight ratio of lythidathion, amino-oligosaccharide and humus is 5-10:1:5-10.
As preferably, the weight ratio of described lythidathion, amino-oligosaccharide and humus is 10:1:6.
Described composition pesticide is prepared into granule.
Synergistic effect of the present invention is obvious, and promote that diseased plant takes root slow seedling, namely the plant be injured grew new root in 10-15 days, and the lasting period reaches more than 2 months.
Embodiment
Be described further technical scheme of the present invention and technique effect below in conjunction with concrete example, the percentage in embodiment is all weight percentage.
One indoor joint toxicity measuring experiment
Test with lythidathion, amino-oligosaccharide and humus three kinds of single doses medicament in contrast, and according to No. 5, following proportions mixture No. 1-mixture:
No. 1, lythidathion: amino-oligosaccharide: humus=15:1:3
No. 2, lythidathion: amino-oligosaccharide: humus=5:1:5
No. 3, lythidathion: amino-oligosaccharide: humus=10:1:6
No. 4, lythidathion: amino-oligosaccharide: humus=8:1:10
No. 5, lythidathion: amino-oligosaccharide: humus=1:1:1
Test take Meloidogyne incognita as examination worm, blank is set, dip method is adopted to carry out toxicity test and do statistical analysis lythidathion, amino-oligosaccharide and humus and above-mentioned 5 mixtures, the synergistic effect of pharmacy mix is evaluated according to co-toxicity coefficient method (CTC), namely CTC≤80 are antagonism, 80<CTC<120 is summation action, and CTC >=120 are synergistic effect.Final statistics is as shown in the table:
| Reagent agent | Proportioning | LC 50(mg/L) | Co-toxicity coefficient |
| Lythidathion (A) | / | 1.07 | / |
| Amino-oligosaccharide (B) | / | 12.53 | / |
| Humus (C) | / | 35.26 | / |
| A:B:C | 15:1:3 | 1.66 | 80.7 |
| A:B:C | 5:1:5 | 1.57 | 143.1 |
| A:B:C | 10:1:6 | 1.05 | 168.7 |
| A:B:C | 8:1:10 | 2.01 | 120.6 |
| A:B:C | 1:1:1 | 4.05 | 71.0 |
As seen from the above table, show synergistic effect when the weight ratio of lythidathion, amino-oligosaccharide and humus is 5-10:1:5-10, when wherein weight ratio is 10:1:6, synergy is the most remarkable.
Two land for growing field crops effect experiments
With the root-knot nematode diseased plant in banana nursery for subjects, following 5 experimental group are set:
Invention group: 5% lythidathion amino-oligosaccharide humus GR, wherein, the weight ratio of lythidathion, amino-oligosaccharide and humus is 10:1:6;
Medicament control group 1:5% lythidathion GR single dose;
Medicament control group 2:1% amino-oligosaccharide GR single dose;
Medicament control group 3:5% humus GR single dose;
Blank.
The process for producing granula of foregoing invention group and medicament control group is, by active ingredient and bentonite mixing granulation, now joins and first uses.During use, consumption is set according to active ingredient equal cost.Caused harm by root-knot nematode, and plant starts medication when there is undergrowth, within after medicine 10 days, 15 days, 20 days and 40 days, investigate experimental result respectively, outcome record and statistics are as shown in following two statistical forms, plant height growth rate (%) in table is that after medicine, plant height is divided by the percentage of plant height before medicine, and preventive effect (%) is that contrast calculates with blank.
