[0022] Biological Assay Example 1: Indoor Toxicity Determination of Fludioxonil and Prochloraz to Cucumber Botrytis cinerea

[0023] Test object: Cucumber Botrytis cinerea collected from the field

[0024] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. Cucumber Botrytis cinerea bacterial strain is cultivated with PDA medium, until bacterial colony grows to 3 / 4 hours of petri dish, is punched from the edge with the hole puncher that inner diameter is 5mm, and the mycelium piece that makes is used as inoculum. Take 5 mL of the prepared drug solution and mix them with quantitative 75 mL of sterilized medium to make 4 drug-containing plates, and use the same amount of sterile water mixed with the medium as a control. Put the hyphae upside down and connect them to the center of the plate, and culture them in a 28°C incubator. After 96 hours, the colony diameter was measured by the cross method, and t...

[0035] Biological Assay Example 2: Indoor Toxicity Determination of Fludioxonil and Iprodione Compound to Tomato Botrytis Botrytis

[0036] Test object: Tomato Botrytis cinerea collected from the field

[0037] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. The test and statistical methods are the same as those in Bioassay Example 1. The results of the toxicity test are shown in Table 2.

[0038] The measurement results show that the ratio of fludioxonil and iprodione between 50:1 and 1:50 has a synergistic effect on Botrytis cinerea, especially when the ratio is between 20:1 and 1:20, the synergistic effect is more obvious , the co-toxicity coefficient is above 165.

[0042] Bioassay Example 3: Indoor Toxicity Determination of Fludioxonil and Procymidone Compounded against Botrytis cinerea

[0043] Test object: botrytis cinerea collected from the field

[0044] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006", mycelium growth rate method. The test and statistical methods are the same as those in Bioassay Example 1. The results of the toxicity test are shown in Table 3.

[0045]The results (Table 3) show that fludioxonil and procymidone have a synergistic effect on botrytis cinerea at a ratio of 50:1 to 1:50, and the co-toxicity coefficients are all above 120.

Abstract

The invention relates to an agricultural bactericidal composition which is prepared by compounding fludioxonil (A) and any (B) of other active ingredients such as prochloraz, pyrimethanil, procymidone, iprodione, dimethachlon and diethofencarb, wherein the mass proportion between A and B is 50:1-1:50, and the rest components are auxiliary elements that are allowed to be used in pesticide and can be accepted. The bactericidal composition can be made into wetting powder, missible oil, suspending agent, water dispersible granules, emulsion in water, microemulsion and the like by the known method. After A is compounded with B according to a certain proportion, the bactericidal composition has remarkable synergistic effect and can be used for controlling gray mold of crops.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing fludioxonil. Background technique [0002] In recent years, due to single drug use and other unscientific drug use methods, a variety of crop pathogens such as powdery mildew and Botrytis cinerea have developed resistance, which has become a major problem in chemical control. Due to the resistance of the bacteria, frequent application of pesticides, increased burden on farmers and increased environmental pollution. According to research reports at home and abroad, Botrytis cinerea has developed resistance to pesticides such as pyrimethanil, diethofencarb, procymidone, and iprodione. In order to meet people's increasingly higher requirements for food safety and living environment, to delay the emergence of bacterial resistance, and to effectively utilize existing pesticide resource resources, it is of great significance to develop new pe...
