Problems solved by technology

The application of triazole fungicides during the growth of apple trees is also prone to resistance, especially when some common triazole fungicides (thiram, carbendazim and thiophanate-methyl) are applied alone in places with severe spotted leaf fall It has been useless, and the yield and quality of apples have been seriously affected. In some places, fruit trees have even failed to harvest.

Abstract

The invention discloses a difenoconazole copper complex shown as a general formula (I): Cu(C19H17Cl2N3O3)2(L)2.nH2O(1), in which C19H17Cl2N3O3 is difenoconazole, L is an acetate radical, a formate radical or a nitrate radical, and n is 0, 1 or 3. The synthesized difenoconazole copper complex has higher activity of inhibiting common fungi on crops than the difenoconazole, thereby being higher in the biological activity, wider in the bactericidal spectrum and smaller in the drug dose.

Description

technical field [0001] The invention relates to a difenoconazole copper complex and a preparation method and application thereof, belonging to the technical field of chemical pesticides. Background technique [0002] Triazole fungicides are high-efficiency, broad-spectrum, long-lasting, low-toxicity, safe, and have good systemic, protective and therapeutic effects, as well as certain plant growth regulating activity. Most of the triazole fungicides are systemic fungicides, which have strong biological activity against pathogenic bacteria, are harmless to plants, and are easy to use. A disease, the effect is excellent. Based on this, the research on triazole fungicides has become an important milestone in the development of pesticide fungicides. [0003] Drug resistance, also known as drug resistance, refers to the resistance of microorganisms, parasites, and tumor cells to chemotherapy drugs. Once drug resistance occurs, the chemotherapy effect of drugs will be significant...
