With mixture airslide disintegrating mill (ULMAX 18BU-9N, the air capacity: about 10Nm that obtains
3/ h, grindability: about 90kg/hr, NISSO ENGINEERING corporate system) pulverize once more after, with ribbon mixer (1000W * 3000L, 4.0m
3, 7.5kw, NISSOENGINEERING corporate system) to mix 60 minutes, the preparation average grain diameter is the wetting powder 1 of 6.58 μ m.
(the 1 preventing and removing effect of rice blast validation test of test example)
For the wetting powder 1 that obtains among the embodiment 1,, carry out following test in order to detect preventive effect to rice blast.
The sowing rice (kind: seed OM1490) (180kg/ha), cultivate rice, make the morbidity of leaf blast disease or fringe rice blast, at this, scatter above-mentioned wetting powder 1 according to the dosage shown in the following table on following opportunity.
* for the leaf blast disease, the disease of leaf reaches at 20% o'clock
* for fringe rice blast, before bloom 7 days
Preventive effect by disease (desease incidence) and 1 pair of rice blast of disease index assessment wetting powder (the sick and fringe rice blast of leaf blast).
A) leaf blast disease
(i) disease (desease incidence)
Disease be before scattering 1 day of wetting powder 1, scatter 7 days after, the number of the leaf of detection of cancerous leaf blast disease respectively after 14 days and after 21 days, estimate by the numerical value of calculating by following formula (1).It is the results are shown in following the 2nd table.
[several 1]
[table 1]
(ii) disease index
Before scattering 1 day of wetting powder 1, scatter 7 days after, after 14 days and after 21 days, check 3 leaves on the top of 50 strain rice respectively.Then, calculate the disease index of leaf blast disease by following formula (2).It is the results are shown in following the 3rd table.
[several 2]
In the formula, N represents the sum of the leaf checked, n
1Expression be equivalent to the mark sheet number of the leaf that is 1 leaf blast disease, n
3Expression be equivalent to the mark sheet number of the leaf that is 3 leaf blast disease, n
5Expression be equivalent to the mark sheet number of the leaf that is 5 leaf blast disease, n
7Expression be equivalent to the mark sheet number of the leaf that is 7 leaf blast disease, n
9Expression be equivalent to the mark sheet number of the leaf that is 9 leaf blast disease.
In addition, the scoring of leaf blast disease is as follows.
1: to the influence of leaf less than 1% situation
3: to the influence of leaf less than 5% situation
5: to the influence of leaf less than 25% situation
7: to the influence of leaf less than 50% situation
9: to the influence of leaf is situation more than 50%
[table 2]
B) fringe rice blast
Before results 7 days, check 50 flowers, the number of the fringe of detection of cancerous fringe rice blast.Then, calculate the disease of fringe rice blast by following formula (3).
[several 3]
In addition, calculate the disease index by following formula (4).Its result is shown in following the 4th table in the lump.
[several 4]
In the formula, N represents the sum of the flower checked, n
1Expression be equivalent to the mark number of the flower that is 1 fringe rice blast, n
2Expression be equivalent to the mark number of the flower that is 2 fringe rice blast, n
3Expression be equivalent to the mark number of the flower that is 3 fringe rice blast, n
4Expression be equivalent to the mark number of the flower that is 4 fringe rice blast, n
5Expression be equivalent to the mark number of the flower that is 5 fringe rice blast.
In addition, the scoring of fringe rice blast is as follows.
1:1,2 affected situations of small ear
2: to the influence of small ear less than 30% situation
3: the influence to small ear is the situation below 60% more than 30%
4: the influence to small ear surpasses 60% situation
5: to paniculiform influence is situation more than 1
[table 3]
By above result as can be known, the wetting powder 1 of embodiment 1 does not have disease, and any one to leaf blast in the sick and fringe rice blast all has good preventive effect.
(test example 2 phytotoxicity tests)
In order to estimate the poisoning of wetting powder 1, observe after 2 days that scatter wetting powder 1, after 4 days and the state of the rice after 7 days.
The average evaluation that rice is not seen poisoning for " 1 ", rice withered average evaluation be " 9 ", estimate with 1～9 these 9 grades.Evaluation result is shown in following the 1st table.
[table 4]
By above result as can be known, the wetting powder 1 of embodiment 1 and microbicide compositions in the past etc. are same, do not see poisoning.
(embodiment 2)
Thiophanate-methyl and tricyclazole with after the ratio solvent shown in the table 5 is in DMF (being added with 1.5%Tween20), are adjusted into the concentration shown in the table 5 with the deionized water that is added with 0.02%Tween20, the preparation soup.
Use perfume burner to the whole above-mentioned soup that scatters q.s of the rice alms bowl of about 3.5 leaf age phases, after soup was air-dry, (strains tested: Pyriculariaoryzae Po-5 strain) suspension (about 5 * 10 to the whole spray inoculation magnaporthe grisea spore of strain
4Individual/as ml), under the moist room condition (acrylic acid box) of 23 ℃ of thermostatic chambers, to leave standstill.Open the lid after about 20 hours, in this thermostatic chamber, leave standstill to make it dry status.After 7 days or after 8 days, fully launch 3rd leaf of leaf or the scab number of 4th leaf when checking inoculation in inoculation, calculate the valency of preventing and kill off.It is the results are shown in table 5.
As shown in table 5, obtained following result: used the theoretical value of preventing and kill off price ratio Colby of treatment region of the soup that contains thiophanate-methyl and tricyclazole big.
[table 5]
(embodiment 3)
After being dissolved in thiophanate and tricyclazole among the DMSO with the ratio shown in table 6～7, the solution that obtains is dissolved in the PDA medium in the mode that reaches concentration shown in table 6～7, makes agar plate.After making agar plate, the flora dish (bacterium Cong デ イ ス Network) (diameter 4mm) of Pyricularia oryzae Po-5 strain is put bed cultivate.20 ℃ leave standstill 10 days after, measure the flora diameter, obtain mycelial growth inhibition rate.It is the results are shown in table 6～7.Shown in table 6～7, obtained following result: used the mycelial growth inhibition rate of treatment region of the agar plate (soup) that contains thiophanate-methyl and tricyclazole bigger than the theoretical value of Colby.
[table 6]
[table 7]
By above result as can be known, with thiophanate-methyl and tricyclazole, can obtain synergy by also.
