- Test Example 1 Effect of increasing the number of stems of rice (promoting tillering) One test grain (50 square meters, average 1250 paddy rice) after transplanting rice with 1 granule containing fulvendiamide of the prescribed dose 10 days after transplanting After spraying, 10 strains were randomly examined 43 days after transplantation, and the core wilt rate / strain and the control rate against scallop, and the number of stems / strain and the number of stems increased by Scirpophaga incertulas were calculated. Note that chlorantraniliprole having the same insecticidal effect was used as a target drug in order to eliminate the sound growth of paddy rice due to the insecticidal effect. The results are shown in Table 1.
- flubendiamide and chlorantraniliprole have the same core withering rate and control rate of scallops by scallop, and increase the number of stems per plant when there is no plant growth regulation effect. It is considered that there is no significant difference between the two treatments and the untreated area.
- Chloranthraniliprole has about 4 stems per strain compared to the untreated group, and the rate of increase in the number of stems is about 120%, whereas fulvendiamide shows the number of stems per strain compared to the untreated group. All the doses show an increase of around 17 and the rate of increase in the number of stems is clearly about 170 to 180%, which is clearly significant.
- the rate of increase in the number of stems in chlorantraniliprole is considered to have an effect of increasing the number of stems due to the control effect on corn borer that damages the stalk of rice.
- the regulatory effect is thought to promote the tillering of paddy rice and to increase the number of stems. This effect of increasing the number of stems of fulvendiamide eventually increases the yield of the harvested rice.
- Test Example 2 Rooting promotion of paddy rice and plant length elongation effect After pouring a 0.7% agar solution containing 25 ppm of fulvendiamide into a glass cylinder (diameter 3 cm x 10 cm) and solidifying it, rice (variety: Nipponbare) Ten buds were sown. Thereafter, the upper part was covered with Japanese paper and left in a constant temperature room at 25 ° C. (16 hours light period 8 hours dark period, relative humidity 60-70%). Eight days after sowing, the root length of the longest root (main root) coming out from the seed pod and the length of the foliage were measured, and the average value was obtained. Moreover, each increase rate when the non-treatment section was set to 100 was calculated. The results are shown in Table 2.
- Test Example 2 is a laboratory test and is not affected by pests. It represents the plant growth regulation effect of fulvendiamide purely. From the results shown in Table 2, the root and stem elongation effects are 160% and 170%, respectively, in comparison with the untreated group, indicating that fulvendiamide has an excellent plant growth regulating effect.
- Test Example 3 Increased yield of rice (increased number of spikes and pods) 6.5 ⁇ 7 leaves of rice (variety: Takanari) transplanted to each treatment area of paddy field divided by 1m 2 , 2 days or 12 days after transplanting A prescribed dose of fulvendiamide granules was processed. The test was conducted in one ward four-running system, rice was harvested 100 days after transplanting, the number of spikes per strain and the number of pods per strain were measured, and the average value was obtained. Moreover, each increase rate when the non-treatment section was set to 100 was calculated. The results are shown in Table 3.
