Amino-oligosaccharin has multiple benefits, including promoting plant growth, enhancing disease resistance, regulating immunity, and improving soil conditions. It is widely used in agricultural production. To achieve better fungicidal effects, amino-oligosaccharin is often mixed with suspension concentrates (SC). However, amino-oligosaccharin is a cationic compound and tends to undergo charge neutralization with anionic surfactants in suspension concentrates, leading to flocculation and precipitation, which impairs efficacy. To address this issue, our company has launched a specialized compatibility agent, SP-6967.

1. Specialized tank-mix compatibility agent, developed specifically to solve the flocculation and precipitation problem caused by mixing amino-benzenesulfonic acid with suspension concentrates (SC). It improves the poor tank-mix compatibility between the two in different scenarios.
2. Effectively enhances the long-term stability of the spray solution when mixing pesticides with fertilizers, solving the problem of inflexible combinations involving amino-benzenesulfonic acid products.
3. Possesses inherent wetting and penetrating properties, thus can be used as a performance-enhancing adjuvant without the need for additional wetting/spreading/penetrating adjuvants in the tank.
4. Recommended dilution ratios: 100–500× for UAV aerial spraying, and 500–1000× for conventional ground spraying.
5. In different application scenarios, safety tests should be conducted before use to prevent phytotoxicity.
A tank-mix compatibility test was conducted using 5% amino-oligosaccharin AS (aqueous solution) and 40% epoxiconazole SC. The test conditions were: 1× hard water, constant temperature water bath at 30°C. The test schemes and results are as follows:

Test results: Direct mixing of 5% amino-oligosaccharin AS and 40% epoxiconazole SC resulted in flocculation and precipitation after 1 hour of standing, and the precipitation persisted. After adding SP-6967 at 500× dilution to the tank-mix, no significant precipitation was observed after 1 hour, and only <0.1 ml of slight precipitate appeared after 4 hours, indicating significantly improved stability. SP-6967 effectively solves the flocculation and precipitation problem when mixing 5% amino-oligosaccharin AS with 40% epoxiconazole SC, ensuring the efficacy of the tank-mix application.
