Description
Technical Field
The invention relates to a pesticide sterilization composition and the application field thereof, in particular to a sterilization composition containing chlorobromoisocyanuric acid and tricyclazole.
Background
The chlorobromoisocyanuric acid, also known as Deminxin bactericide king, Xiaojunling, Junduqing, Bixiudan and the like, can slowly release hypobromous acid and hypochlorous acid when being sprayed on the surfaces of crops, has four times of activity of the hypobromous acid, and has strong capability of killing bacteria and fungi. The compound is sprayed on crops, and the parent body after the hypobromous acid is released through systemic conduction forms the triazine diketone and the triazine, so that the compound has a strong virucidal effect; in addition, the starting material is rich in potassium salt and trace elements, so that chlorobromoisocyanuric acid has strong capability of preventing and killing bacteria, fungi and viruses. Chlorobromoisocyanuric acid is a low-toxicity bactericide and is widely used for the house control of plant diseases.
Tricyclazole, english name: the tricyclazole is mainly used for preventing and controlling rice blast. The mechanism of action is to prevent the invasion of adherent spores mainly by inhibiting melanin synthesis. Can be quickly absorbed by each part of the rice, has long lasting period, stable drug effect and rain wash resistance.
Tricyclazole has been a main agent for controlling rice blast, and is mainly based on two aspects, namely, low price and acceptance by farmers, and after years of use, the effect of tricyclazole on controlling rice blast is accepted by users, but the effect is influenced by the resistance of crops after years of continuous use, and tricyclazole is a protective bactericide and has little killing effect on rice blast pathogens which invade into cell tissues.
In agricultural production, the active ingredients of pesticides with different action mechanisms are mixed, and the method is a common method for preventing and treating agricultural resistant diseases. Through pesticide formula screening, the formula with obvious synergy is beneficial to improving prevention and control, reducing agricultural cost and delaying the development of disease resistance, and is an important means for comprehensively treating diseases. At present, no relevant report is found in the research of applying the composition taking chlorobromoisocyanuric acid and tricyclazole as effective components to rice blast

The test method comprises the following steps: refer to agricultural industry Standard NY/T1154.7-2006 of the people's republic of China, potting method. Selecting three-leaf stage rice seedlings with consistent growth vigor, and selecting 5 pots of test rice seedlings for each treatment. Culturing Magnaporthe grisea on agar culture medium of tomato and oat, washing spores with sterile water after spore production to prepare suspension of 1 × 105 spores/mL, uniformly spraying and inoculating on rice seedlings to be tested, and covering a black plastic bag for moisture preservation and culture for 24 h. 24h after inoculation, the treatment with agents was carried out, each agent being set to 5 concentration gradients and sprayed at 50PSI pressure using a spray tower. After spraying the pesticide, the rice seedlings are cultured under the conditions of about 25 ℃ and the relative humidity of more than or equal to 90 percent, the disease occurrence condition is investigated 7 days after the pesticide is sprayed according to the disease occurrence grading standard of the rice blast, and the prevention and control effect is calculated.
Measuring EC 50 values of different agents to strains by adopting a hypha growth rate method indoors, calculating a co-toxicity coefficient (CTC) of the mixture according to a co-toxicity coefficient calculation method, and determining the synergy of the mixture, wherein the specific calculation method comprises the following steps:
taking a single dose of the mixture as a standard medicament (generally, the lower EC 50 is selected), the following calculation is carried out:
single dose virulence index (standard dose EC 50/single dose EC 50 × 100)
The theoretical virulence index is the virulence index of A single agent multiplied by the proportion of A single agent in the mixed preparation plus the virulence index of B single agent multiplied by the proportion of B single agent in the mixed preparation
Measured virulence index (EC 50 value of standard single dose/EC 50 value of mixed dose x 100
Co-toxicity coefficient is measured toxicity index/theoretical toxicity index multiplied by 100
Grading co-toxicity coefficients: the mixture has synergistic effect when CTC is greater than 120, is antagonistic when CTC is less than 80, and has additive effect between 80 and 120.
Table 1 chlorobromoisocyanuric acid and tricyclazole in combination with rice blast pathogen combined virulence test:
according to the indoor toxicity test results, the ratio of the chlorobromoisocyanuric acid to the tricyclazole has a good synergistic effect when the ratio is 1-60: 45-1, wherein the highest co-toxicity coefficient is 245.18 when the ratio of the chlorobromoisocyanuric acid to the tricyclazole is 3: 2, and the synergistic effect is considered to be the best when the ratio of the chlorobromoisocyanuric acid to the tricyclazole is 3: 2.
And further performing field efficacy test on the preparation with the ratio of chlorobromoisocyanuric acid to tricyclazole of 3: 2 to evaluate the field practical application effect.
