Abstract
The invention relates to a composition for controlling rice diseases and pest insects at a seedling raising stage. The active ingredients include chitin, probenazole and humic acid, wherein a weight ratio of the chitin to probenazole to humic acid is (20-40):(1-2):(80-100). Compared with the prior art, the composition disclosed by the invention has the advantages that the chitin, probenazole and humic acid are mixed according to a specific ratio, so that the inhibitory and synergistic effects on rhizoctonia solani are obvious, and the composition is excellent in control effect and contributes to reduction in the pesticide application amount and reduction in the pesticide cost.
Description
Technical field
The present invention relates to agricultural technology field, specifically a kind of compositionss of preventing and treating raising rice seedlings phase pest and disease damage.
Background technology
Dry rice seedling technology is the first-selected seedling-cultivation technique in current Rice Cropping area.With dry rice seedling mode seedling, due to aqueous vapor
The change of ratio, result in the change of rice shoot root system environment, and the anaerobic condition of script watery ricenursery there occurs transformation, the kind of pest and disease damage
Class correspondingly there occurs change.Compared with watery ricenursery, dry rice seedling root system is elongated, easily causes wound, disease under good environment of breathing freely
Bacterium breeding is very fast, more easily causes seedling and catches an illness.Therefore, Dry Breeding Seedlings striped rice borer, yellow rice borer disease and mitigation, bakanae disease, vertical withered
Sick sickness rate is multiplied, and especially damping-off easily breaks out.
At present, also do not retrieve the correlation that chitin, probenazole and humic acid are used in combination preventing and treating rice pest
Open.
Content of the invention
The technical problem to be solved of the present invention is to provide a kind of compositionss of preventing and treating raising rice seedlings phase pest and disease damage, can
Synergistically control rice shoot pest and disease damage.
The technical solution used in the present invention is as follows：
A kind of compositionss of preventing and treating raising rice seedlings phase pest and disease damage, effective ingredient is by chitin, probenazole and humic acid
Composition, the part by weight of chitin, probenazole and humic acid is 20-40:1-2:80-100.
As optimal case, the part by weight of described chitin, probenazole and humic acid is 30:1:80.
Described compositionss are prepared into granule.
Compared with prior art, the present invention, by chitin, probenazole, humic acid mixture according to a specific ratio, opposes
Substantially, not only control effect is good for the suppression potentiation of rot bacterium, and advantageously reduces applications of pesticide amount and reduce pesticide cost.
Specific embodiment
With reference to embodiments technical scheme and beneficial effect are described further, of the present invention hundred
Divide ratio in addition to Special Statement, be all weight percentage.
First, chitin, the probenazole and humic acid and built agent Toxicity Determination to rice seedling blight
Determine through prerun after each medicament effective inhibition concentration scope, by chitin, probenazole and humic acid and its mixed
Ingredients is pressed active constituent content gradient series and is diluted 5 concentration, if clear water comparison.Reference《Farm-chemical indoor determination test is accurate
Then antibacterial》Carry out, the virulence to rice seedling blight for the medicament is measured using mycelial growth rate method.Crossing method is used after 72h
Measurement colony diameter, calculates each process net growth, mycelial growth inhibition rate.
Mycelial growth inhibition rate is converted into probit value (y), liquor strength (μ g/mL) is converted into logarithm value (x), with minimum
Square law tries to achieve virulence regression equation (y=a+bx), and thus calculates the EC of every kind of medicament50Value.
Evaluating the potentiation of pharmacy mix, that is, CTC≤80 are antagonism to co-toxicity coefficient method (CTC) according to the abundant method of Sun Yun
Effect, 80<CTC<120 is summation action, and CTC >=120 are potentiation.Statistical result is as shown in table 1：
| Reagent agent | Proportioning | EC50(mg/L) | Co-toxicity coefficient (CTC) |
| Chitin (A) | / | 9.44 | / |
| Probenazole (B) | / | 1.05 | / |
| Humic acid (C) | / | 6.81 | |
| A：B：C | 20:0.5:80 | 7.65 | 91.6 |
| A：B：C | 20:1:80 | 4.04 | 168.7 |
| A：B：C | 20:2:50 | 8.17 | 77.5 |
| A：B：C | 20:2:80 | 5.19 | 124.6 |
| A：B：C | 20:1:100 | 4.22 | 161.5 |
| A：B：C | 30:1:80 | 3.98 | 175.7 |
| A：B：C | 30:2:100 | 4.15 | 160.9 |
| A：B：C | 40:1:80 | 5.27 | 135.6 |
| A：B：C | 40:1:100 | 5.20 | 136.4 |
Measurement result shows, the part by weight of chitin, probenazole and humic acid is 20:0.5:When 80, in addition
Effect；The part by weight of chitin, probenazole and humic acid is 20:2:When 50, in antagonism；During other weight ratios,
It is shown as potentiation, wherein part by weight is 30:1:80 potentiations are the most obvious.
2nd, Application Example
(1) preparation of product：
The product of described below is all conventionally prepared into granule.
Test group 1：Raw material according to following percentage by weight is made：Chitin 15%, probenazole 0.5%, humic
Acid 40%, excipient supplies 100%.
Test group 2：Raw material according to following percentage by weight is made：Chitin 15%, probenazole 1%, humic acid
50%, excipient supplies 100%.
Test group 3：Raw material according to following percentage by weight is made：Chitin 20%, probenazole 1%, humic acid
60%, excipient supplies 100%.
Test group 4：Raw material according to following percentage by weight is made：Chitin 20%, probenazole 0.5%, humic
Acid 80%, excipient supplies 100%.
Matched group 1：Raw material according to following percentage by weight is made：Chitin 20%, probenazole 2%, humic acid
50%, excipient supplies 100%.
Matched group 2：Blank.
(2) application process
Respectively by the product of above-mentioned test group 1-4 and matched group 1-2 gained and seedling raising ground substance according to weight than for 1:6 mixing
Uniformly, it is mixed into rice wilt pathogens in seedling raising ground substance in advance；Seedling, seedling phase are carried out respectively using the seedling raising ground substance after handling well
Between keep other seedling environment consistent, and be managed collectively, do not use any pesticide.
(3) result of the test
After planting 15 days, in conjunction with the investigation of rice shoot damping-off high-incidence season result, calculate damping-off control effect and rice shoot is final
Planting percent, result statistics is as shown in the table：
| Treatment group | Sickness rate (%) | Prevention effect (%) | Planting percent (%) |
| Test group 1 | 3.98 | 87.62 | 91.72 |
| Test group 2 | 4.55 | 85.85 | 90.58 |
| Test group 3 | 5.15 | 83.99 | 91.49 |
| Test group 4 | 6.12 | 80.97 | 90.22 |
| Matched group 1 | 28.65 | 10.91 | 60.37 |
| Matched group 2 | 32.16 | / | 61.4 |
As can be seen that test group 1-4 to rice shoot damping-off potentiation substantially, had both reduced making of effective ingredient from result of the test
Consumption, shows the field efficacy better than matched group 1-2 again, contributes to reducing Pesticide use cost.
