According to the method for control of the present invention, can obtain good preventive effect to various crop pests, especially rice blast.In addition, crop pest applicable time of preventing and kill off is also long.Therefore, the degree of freedom in the period of using of agent for preventing and eliminating (agricultural or horticultural use microbicide compositions) is high.
Embodiment
Below, by embodiment, the present invention is described in further detail.But the present invention is not subjected to any restriction of these embodiment.
(embodiment 1)
In kaolinite clay 18.6 weight portions, add 1: 1 (weight ratio) mixture (FPP-03102 of polyoxyethylene triphenylethylene base phenyl ether and precipitated silica, Japan emulsifier company system) 3.0 weight portions, polycarboxylate (Newkalgen-WG-5, this grease of bamboo company system) 1.0 weight portions, thiophanate-methyl (TOD-019P, Japan Cao Da company system) 36.7 weight portions and tricyclazole 40.7 weight portions, with ribbon mixer (1000W * 3000L, 3.8m
3, 7.5kw, NISSOENGINEERING company system) mixed 60 minutes.
The mixture that obtains is pulverized with the high speed impact cracker (Contraplex 250CW, main body side: 11200rpm, reveal: 2800rpm, grindability: about 180kg/hr, HosokawaMicron company system) that declines.Then, this crushed material is used again ribbon mixer (1150W * 3500L, 4.0m
3, 5.5kw, NISSO ENGINEERING company system) mix.
With the mixture that obtains with airslide disintegrating mill (ULMAX 18BU-9N, air capacity: about 10Nm
3/ h, grindability: about 90kg/hr, NISSO ENGINEERING company system) again pulverize after, with ribbon mixer (1000W * 3000L, 4.0m
3, 7.5kw, NISSOENGINEERING company system) to mix 60 minutes, the preparation average grain diameter is the wetting powder 1 of 6.58 μ m.
(test example 1 preventing and removing effect of rice blast validation test)
For the wetting powder 1 that obtains in embodiment 1, in order to detect the preventive effect to rice blast, carry out following test.
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 on following opportunity according to the dosage shown in following table.
* sick for leaf blast, when the disease of leaf reaches 20%
* 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 (leaf blast disease and fringe rice blast).
A) leaf blast is sick
(i) disease (desease incidence)
Disease be before scattering 1 day of wetting powder 1, scatter 7 days after, after 14 days and detect respectively the number of the leaf of suffering from the leaf blast disease after 21 days, estimated by the numerical value of calculating by following formula (1).To 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 respectively 3 leaves on the top of 50 strain rice.Then, calculate the disease index of leaf blast disease by following formula (2).To the results are shown in following the 3rd table.
[several 2]
In formula, N represents the sum of the leaf that checks, 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: on the impact of leaf less than 1% situation
3: on the impact of leaf less than 5% situation
5: on the impact of leaf less than 25% situation
7: on the impact of leaf less than 50% situation
9: be situation more than 50% on the impact of leaf
[table 2]
B) fringe rice blast
Before results 7 days, check 50 flowers, detect the number of the fringe of suffering from 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).It is the results are shown in following the 4th table.
[several 4]
In formula, N represents the sum of the flower that checks, 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: on the impact of small ear less than 30% situation
3: the impact on small ear is the situation below 60% more than 30%
4: the impact on small ear surpasses 60% situation
5: be situation more than 1 on paniculiform impact
[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 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 had no 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, have no poisoning.
(embodiment 2)
Thiophanate-methyl and tricyclazole with after the ratio solvent shown in table 5 is in DMF (being added with 1.5%Tween20), are adjusted into the concentration shown in table 5 with the deionized water that is added with 0.02%Tween20, the preparation liquid.
Use perfume burner to the about whole above-mentioned liquid that scatters q.s of rice alms bowl of 3.5 Leaf-Age-Periods, after liquid was air-dry, (strains tested: Pyriculariaoryzae Po-5 strain) suspension (approximately 5 * 10 to the whole spray inoculation magnaporthe grisea spore of strain
4Individual/ml), lower standing in the moist room condition (acrylic acid box) of 23 ℃ of thermostatic chambers.Approximately open the lid after 20 hours, carry out standing to make it dry state in this thermostatic chamber.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 preventive effect.To the results are shown in table 5.
As shown in table 5, obtained following result: used the preventive effect for the treatment of region of the liquid that contains thiophanate-methyl and tricyclazole larger than the theoretical value of Colby.
[table 5]
(embodiment 3)
After being dissolved in thiophanate and tricyclazole in 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.After standing 10 days, measure the flora diameter at 20 ℃, obtain mycelial growth inhibition rate.To the results are shown in table 6～7.As shown in table 6～7, obtained following result: used the mycelial growth inhibition rate for the treatment of region of the agar plate (liquid) that contains thiophanate-methyl and tricyclazole larger 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.
