86.7 parts by weight of the suspension and 13.3 parts by weight of the thickener-containing liquid were mixed to obtain SC comprising 10% by weight of mefentriflu-conazole (hereinafter referred to as mefentrifluconazole SC).
86.7 parts by weight of the suspension and 13.3 parts by weight of the thickener-containing liquid were mixed to obtain SC comprising 10% by weight of mefentriflu-conazole (hereinafter referred to as mefentrifluconazole SC).
[0030] Efficacy Test Example 1 Liquid compositions comprising 150 ppm of mefentrifluconazole, 2 or 6% by volume of an oil adjuvant and water (hereinafter referred to as Present Composition 1 and Present Composition 2) were prepared by diluting mefentrifluconazole SC
and an oil adjuvant (COC: Agri-Dex, containing 82% of heavy range paraffinic oil, 17%
of surfactant, and 1% of other components, manufactured by Helena), respectively, with water and mixing them. Similarly, mefentrifluconazole SC and an oil adjuvant were each diluted with water to prepare a liquid composition comprising 150 ppm of mefen-trifluconazole and water (hereinafter referred to as Comparative Composition 1), a liquid composition comprising 2% by volume of an oil adjuvant and water (hereinafter referred to as Comparative Composition 2), and a liquid composition comprising 6%
by volume of an oil adjuvant and water (hereinafter referred to as Comparative Com-position 3), respectively.
A soil was filled into a plastic pot, and wheat (variety: Shirogane) was seeded therein, and grown in a greenhouse for 10 days. The prepared liquid compositions were each sprayed to the foliage of wheat such that the application rate would be 200 L/ha.
After spraying, the plant was air-dried, and an aqueous suspension of spores of Brown rust (P. recondita) was inoculated by spraying it. After inoculating, the plant was placed at 23 C under high humidity for 1 day and subsequently placed under illu-mination for 10 days, then the lesion area was investigated (lesion area in the treated area).
On the other hand, in the non-treated area, the same operation as in the treated area was carried out except that the liquid composition was not sprayed, and the lesion area of Brown rust in the non-treated area was investigated (lesion area in the non-treated area).
From the lesion area in each of the treated area and the non-treated area, the efficacy of the treated area was determined according to the following "Formula 1".
The results are indicated in Table 1.
