Maximum 2 applications per crop season, pre-harvest interval (PHI) is 35 days. No adverse effect on succeeding crops. |
| Maize | Northern corn leaf blight | 15-20 g/mu | Apply as uniform foliar spray before or at the initial stage of northern corn leaf blight occurrence. Apply once every 7-10 days, for 2-3 consecutive applications. Pre-harvest interval (PHI) on maize is 21 days, maximum 2 applications per crop season. |
| Apple Tree | Alternaria leaf spot, Brown spot, Anthracnose leaf blight, Powdery mildew | 2000-fold dilution | Apply routinely to branches and leaves at the recommended dosage before or at the initial stage of disease occurrence, reapply every about 10 days for 3 consecutive times. Ensure uniform spray on the entire apple tree; Pre-harvest interval (PHI) on apple trees is 21 days, maximum 3 applications per crop season. |
| Citrus Tree | Resin disease (Sand bark disease), Anthracnose | 1500-2000-fold dilution | Apply at the initial stage of disease occurrence, ensure uniform and thorough spray; Pre-harvest interval (PHI) on citrus trees is 14 days, maximum 3 applications per crop cycle; |
| Pepper | Anthracnose | 35-50 g/mu | Spray before or at the initial stage of anthracnose occurrence, apply uniformly on pepper plants with an interval of 7-10 days between applications; Maximum 3 applications per crop season, pre-harvest interval (PHI) on pepper is 5 days. |
| Cucumber | Powdery mildew | 28-30 g/mu | Apply before or at the initial stage of powdery mildew occurrence, spray once every 7-10 days, maximum 3 applications per crop season, pre-harvest interval (PHI) is 3 days. |
| Turf | Brown patch | 800-1000-fold dilution | Recommended application before or at the initial stage of brown patch occurrence, with an interval of 7-10 days, 2-4 applications per crop season. |
| Rosaceae Ornamental Flowers | Brown spot | 2000-3000-fold dilution | 2-4 applications per crop season, with an interval of 7-15 days between applications. |
| Peanut | Leaf spot | 20-40 g/mu | Apply at the initial stage of leaf spot occurrence, ensure uniform and thorough spray; Pre-harvest interval (PHI) on peanut is 45 days, maximum 3 applications per crop cycle. |
| Potato | Early blight | 25-40 g/mu | Apply by routine spray method before or at the initial stage of early blight occurrence; No more than 3 applications in the current season, with an interval of 7 days between applications, pre-harvest interval (PHI) is 14 days. |
Visible Absorption
Kelihua® adopts Shentai’s proprietary “Woruo” film-forming technology. It can be completely absorbed by crops within 30 minutes after application, with no need for re-spraying after rain, ensuring more reliable efficacy.
Premium Quality & Stable Performance
Kelihua® features a scientific formulation, advanced production technology, and stable, reliable quality. It has high activity, excellent miscibility, and consistent effectiveness, making it suitable for aerial application.
Disease Prevention & Leaf Protection for Healthier Crops
Kelihua® can delay crop senescence, prolong the photosynthetic period, and enhance crop stress resistance.
It helps maintain healthy functional leaves, promotes grain filling, produces plump kernels, prevents early leaf aging, increases nutrient accumulation in the later stage, and significantly improves both yield and quality.
