Product Usage

Smectazol is a broad spectrum of internal fungicide, the Basidiomycetes and Ascomycetes caused by a variety of diseases have a good protection and treatment, can effectively control wheat crop powdery mildew, rust, smut, corn Smut and so on.

Instructions

Streptomycin has broad-spectrum bactericidal activity, can control cereal crops (mainly wheat, barley, rye, corn, etc.) stems and leaves, spike disease and soil transmission and seed disease, such as powdery mildew, rust, moire Disease, leaf spot, net spot, smut and so on. At the same time, can also prevent soil and seed transmission disease. Effect on cereal powdery mildew.

Nanjing Rongcheng Chemical Co., Ltd. production of 12.5% of the powdery mildew suspension agent can be treated with stem and leaf, but also seed treatment. Use as follows:

1, the best control of wheat powdery mildew for the stalk spike sporadic onset to the disease rise, or the upper three leaf incidence rate of 30% to 50% when the start of spraying, 12.5% per mu with 17% of the suspension (active ingredient 2.13 g), spray the water constant.

2, control wheat smut per l00 kg of seeds with 12.5% suspension 200 ~ 30Oml (active ingredient 25 ~ 37.5 grams) seed dressing. The first amount of fertilizer required to mix the water into the pulp, transferred into the amount of pulp for the seed weight of 1.5%, seed dressing even after planting.

3, the best control of wheat rust treatment period for the large-scale outbreak of wheat rust before, per acre with 12.5% suspending agent 33.3 ~ 50 ml (active ingredient 4.16 ~ 6.25g), water spray or low-volume spray.

4, the prevention and treatment of corn silk smut per l00kg corn seeds with 12.5% suspending agent 320 ~ 480ml (active ingredient 40 ~ 60g) seed dressing. The first amount of fertilizer required to mix the water into the pulp, transferred into the amount of pulp for the seed weight of 1.5%, seed dressing even after planting.

Anhydrous potassium fluoride and 2,3,4,5-tetrachloronitrobenzene in anhydrous dimethylformamide at 140 ° C for 15 hours to prepare 2,4-difluoro-3,5-dichloronitrate And then subjected to reduction reaction with iron powder at 95 to 100 ° C for 8 hours in acetic acid to obtain 2,4-difluoro-3,5-dichloroaniline. 2,6-difluorobenzamide was reacted with oxalyl chloride in toluene for 5 hours to give 2,6-difluorobenzoyl isocyanate, followed by treatment with the above-mentioned 2,4-difluoro-3,5-dichloro Aniline was reacted in toluene at room temperature for 15 hours, and the resulting white solid powder was benzodiazole.
