[0045] Further improvement of the formulation of the aerial spraying synergist in Example 2

[0046] Test method: Dilute and mix the products of different dosage forms produced by our company according to the concentration used in aerial spraying.

[0049] Table 2 Mixing effects of aerial spraying synergists on various ECs and amino acid fertilizers

[0050]

[0051] The mixing of the products self-made by the above applicant and the mixing experiment results of some other commercially available products (not shown) show that both formula 2 and formula 4 of this application can improve the mixing performance, but the improvement amplitude cannot reach the ideal level (in many cases, it cannot be used up within one day after mixing).

[0052] The applicant attempts to introduce rhamnolipid and alkanolamide, which are biosurfactants, on the basis of formula 4, and preferably selects the following improved formulas (only typical formulas are shown, and formulas for a large number of screenings are not shown):

[0053] Formula 4-1: Formula 4 + 3% rhamnolipid + 3% diethanolamide ricinoleate

[0054] Formula 4-2: Formula 4 + 3% rhamnolipid + 3% diethanolamide tallate

[0055] Formula 4-3: Formula 4 + 3% rhamnolipid + 3% diethanolamide coconutate

[0056] Formulation 4-4: Formulation 4 + 5% rhamnolipid

[0057] Formulation 4-5: Formulation 4 + 6% diethanolamide ricinoleate

[0058] Verify the effects according to the schemes of Experiments 1 to 6 in Example 1 above. The results show that for both the system of abamectin EC + hexaflumuron EC + amino acid and the system of emamectin benzoate suspension concentrate + hexaflumuron EC + amino acid, the formulation containing rhamnolipid can extend the stratification time to more than 16 hours. Among them, Formulation 4-1 and Formulation 4-3 can extend the stratification time to about 24 hours, while Formulation 4-5 has basically no improvement compared with Formulation 4.

[0060] 3.1 Experimental object: Rice stem borer

[0061] Experimental method: Select twenty rice plants in the same plot each, and spray them at a dilution concentration of 50 ml per mu for comparison. Mortality rate = number of dead insects / number of insects on the plant, and the result is the average value of the mortality rates of the twenty plants. Products used in the experiment: 2.3% emamectin benzoate suspension concentrate (Jiutong). Experiment 1: Spray 30 ml of 2.3% emamectin benzoate suspension concentrate per mu on rice stem borers. Experiment 2: Spray 30 ml of 2.3% emamectin benzoate suspension concentrate plus 50 ml of stable synergist (Formulation 4-1) per mu on rice stem borers.

[0068]

[0069] After the aerial spraying synergist is used in combination with emamectin benzoate, the control effect on rice stem borers on rice crops is significantly improved, from 60% to about 80%. The effect of formula 4-3 is particularly significant.

Experiment 4: Spray 30 ml of 32.4% dicamba·glyphosate + 30 ml of aerial spraying synergist (formula 4-1) per mu. Experiment 5: Spray 50 ml of 32.4% dicamba·glyphosate + 40 ml of aerial spraying synergist (formula 4-3) per mu.

[0072] Table 5 Synergistic effect of aerial spraying synergist on glyphosate

[0073]

[0074]

[0075] This table shows that compared with direct spraying, in the plots with aerial spraying stabilizer, the weed mortality rate has increased significantly (the effect of 30 mL of glyphosate application can reach the effect of 50 mL), and the effect of formula 4-3 is more significant than that of 4-1. This synergist has an obvious synergistic effect on herbicides, can reduce the dosage of glyphosate, and improve ecological safety and product safety.

[0076] 3.4 Experimental object: Rice stem borers

[0077] In 2021, demonstration fields were established around Muyang County, Suqian City, Jiangsu Province. The experimental object was the rice stem borer. It was combined with the treatment of the aerial spraying synergist of the 5% abamectin (Liufuding) spraying formula 4-3 produced by our company. The experimental doses were as follows: Experiment 1: 30 ml / acre of 5% abamectin EC + 20 ml / acre; Experiment 2: 30 ml / acre of 5% abamectin EC + 40 ml / acre; Experiment 3: 30 ml / acre of 5% abamectin EC + 60 ml / acre; Experiment 4: 30 ml / acre of 5% abamectin EC + 80 ml / acre; Experiment 5: 30 ml / acre of 5% abamectin EC

[0078] + 100 ml / acre; Experiment 6: 30 ml / acre of 5% abamectin EC.

[0080]

[0081]

[0082] After the synergistic stabilizer was used in combination with 5% abamectin EC, the control effect on the rice stem borer was significantly improved with the increase of the concentration of the synergistic stabilizer on rice. The dosage of 60 - 80 mL / acre was the best.
