Embodiment 1

[0043] Take by weighing 300 grams of diacetonamine copper oxalate, 20 grams of cloconazole, 25 grams of TERSPERSE2700 (polycarboxylate, produced by Huntsman, U.S.), 30 grams of sodium lignosulfonate, 20 grams of open powder BX (dibutyl Sodium naphthalene sulfonate), 30 grams of K-12 (sodium lauryl sulfate), 20 grams of PVA (polyvinyl alcohol, molecular weight 2000), 20 grams of polyvinylpyrrolidone, and kaolin make up 1000 grams. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, remixing, and granulation steps to prepare water-dispersible granules with an active ingredient content of 32% diacetonamine copper oxalate·conconazole.

Embodiment 2

[0045] Take by weighing 200 grams of diacetonamine copper oxalate, 200 grams of epoxiconazole, 20 grams of T36 (polycarboxylate), 20 grams of diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 20 grams of open powder BX ( Sodium dibutyl naphthalene sulfonate), 20 grams of K-12 (sodium lauryl sulfate), and attapulgite are added to 1000 grams. The above-mentioned raw materials are prepared through the conventional method of preparing water-dispersible granules, namely mixing, ultra-fine airflow pulverization, re-mixing, and granulation to prepare water-dispersible granules with an active ingredient content of 40% diacetonamine copper-epiconazole oxalate.

Embodiment 3

[0047] Take by weighing 100 grams of diacetonamine copper oxalate, 300 grams of pyraclostrobin, 40 grams of TERSPERSE2700 (polycarboxylate, produced by Huntsman, U.S.), 20 grams of diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate) , 20 carats of open powder BX (sodium dibutylnaphthalene sulfonate), 20 grams of K-12 (sodium lauryl sulfate), 30 grams of cornstarch, 50 grams of ammonium sulfate, and attapulgite are added to 1000 grams. The above raw materials are prepared through the conventional method of preparing water-dispersible granules, ie, mixing, ultrafine airflow pulverization, re-mixing, and granulation to prepare water-dispersible granules with an active ingredient content of 40% diacetonamine copper pyraclostrobin.

Abstract

The invention discloses a bactericidal composition containing diacetone amine copper oxalate and triazole bactericides. The bactericidal composition comprises a first active ingredient, namely diacetone amine copper oxalate, and a second active ingredient, namely one of the triazole bactericides, wherein a weight ratio of the first active ingredient to the second active ingredient is (1:15)-(15:1), and the sum of the content of the first active ingredient and the second active ingredient is 5-90 percent of the total weight of the bactericidal composition. The composition can be prepared into agriculturally allowable forms such as water dispersible granules, wettable powder, dispersible oil suspended agents or micro emulsion. The bactericidal composition disclosed by the invention effectively solves the problem that the effect of eradicating crop diseases by singly using the diacetone amine copper oxalate or the triazole bactericides is not ideal, has an obvious synergistic effect and is high in crop safety. The bactericidal composition disclosed by the invention has good effects of controlling altermaria leaf spot and brown spot of apples, bacterial canker diseases and anthracnose of citruses, downy mildew, powdery mildew and angular leaf spot of cucurbites, false smut, sheath blight and blast of rice, and black point and leaf spot diseases of bananas.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, and relates to a bactericidal composition, in particular to a binary compound bactericidal composition with diacetonamine copper oxalate as the first active ingredient and triazole fungicides as the second active ingredient . The invention also relates to the formulation and application of the fungicidal composition in agriculture. Background technique [0002] Copper preparations are one of the oldest types of agricultural fungicides, which have the advantages of broad antibacterial spectrum and are not easy to produce drug resistance. Inorganic copper preparations mainly composed of copper hydroxide and copper sulfate have been used for more than 200 years, but because they are difficult to be biodegraded, long-term and large-scale use has caused the accumulation of copper in the soil, which will affect the normal growth of plants and adverse effects on soil function. At present,...
