Research on the synergistic effect of humic acid on pesticides, reported in the literature alone, is sufficient to illustrate the significant effects achieved by the combined use of humic acid and pesticides, including pesticides, fungicides, herbicides and plant growth regulators. Specific examples mainly include the use of humic acid in combination with copper or gram to control cucumber downy mildew. Humic acid can increase the effectiveness of copper in cucumber downy mildew by 27.2% and 46.9% in greenhouse and outdoor planting respectively; One-third of the dosage of humic acid can still achieve the control effect of humic acid. Combining fulvic acid with thiophanate-methyl and carbendazim respectively to control peanut leaf spot can achieve different control effects. Increased by 57.8% and 38.8%; combined with Dimethoate to prevent apple fruit rot, the control effect increased by 43.4% 60 days after harvest; sodium humate and omethoate can be used to control aphids. Its aphid killing rate can reach 100%; it has achieved remarkable results when used in combination with herbicides such as weedkiller, fensadex, fenacet and 2.4-D butyl ester, etc. These examples have been able to illustrate that humic acid The synergistic effect of pesticides on agricultural production.
