Rice and wheat leaf-surface-philic substance sourced auxiliary agent and preparation and use method thereof

[0044] Example 1 Preparation of rice-wheat leaf-friendly surface substance source adjuvant

[0045] The pesticide adjuvant consists of the following components by weight percentage:

[0046] Phase A component: whole rice or wheat leaves soaked in 50-55% ethanol water solution (mass ratio 1:6-8) for 10-12 hours;

[0047] Phase B components: 42-46% sodium lauryl sulfate, 1-3% α-amyl alcohol, 1-3% tragacanth gum, 10-12% organic silicon; the balance is 50-55% % ethanol aqueous solution;

[0048] Among them, sodium lauryl sulfate, α-amyresinol, and tragacanth gum were all purchased from Chengdu Mansite Biotechnology Co., Ltd.; organic silicon was purchased from Jiangsu Fengshan Group Co., Ltd.

[0049] Specific application cases: the components of each case are shown in Table 1.

[0053]After the finished product A in the adjuvant is mixed with the finished product B, the pesticide preparation is added and mixed, and then sprayed with water. For example, commercially available 50% pirimicarb pesticide preparation is used to spray on wheat, and the cases of each application method are shown in Table 2.
