Performance evaluation:
1. quality evaluation of smoking agent
The smoke agent prepared in the embodiment 1-8 is put into a constant temperature oven (80 +/-2) DEG C, and observed for 1 time every 2 hours within 72 hours, if the smoke agent is found to be self-ignited, the quality is unqualified, and if the smoke agent is not self-ignited, the smoke agent is qualified.
2. Safety testing of smoke agents
The smoke agents prepared in examples 1-8 were simultaneously ignited by 8 persons wearing protective equipment in the same manner, the time for starting smoking the smoke agent and the time for extinguishing the flame were observed, and the safety of the smoke agent was classified into three grades, i.e., high, medium and low, according to whether sufficient time was left before smoking and whether the flame could be extinguished in time.
3. Moisture resistance and ignition Rate testing of the smoking agent
50 chlorothalonil smoke agents were prepared according to each of examples 1-8, and divided into A, B groups of 25, wherein group A was subjected to an ignition test on the day of preparation and recorded as w1, and group B was placed in the same temperature and humidity environment and subjected to an ignition test 30 days later and recorded as w 2.
4. Test of field drug effect
The test is carried out in a greenhouse, six rows of greenhouses are used for the test, each row of greenhouses is treated for three times, the growth of the cucumbers is basically consistent, and the field management is carried out according to a conventional management method.
The test survey of each greenhouse adopts a five-point sampling method, 10 plants are planted at each point, about 50 leaves are surveyed at each point, the leaves are arranged above, in the middle and below each plant, the grade of the diseased leaves is recorded according to downy mildew grading treatment, the first pesticide application is started at the initial stage of disease attack, the disease condition is surveyed at intervals of 10 days and three times in total at the later stage, and the disease prevention effect is calculated on the fourth day after the third pesticide application.
Prevention and treatment effect calculation mode: relative control effect (%) (control disease means increment-prevention disease means increment)/X100% disease means increment-prevention after disease means prevention before disease means increment
Grading standard of cucumber downy mildew conditions:
| grade | Disease condition |
| Level 0 | No scab |
| Level 1 | 1/10 with sporadic incidence and disease spots with area not exceeding |
| Stage | |
| 2 | The area of the lesion is 1/10-1/5 |
| |
The area of the lesion spots is 1/5-1/3 |
| 4 stage | The area of the lesion spots is 1/3-2/3 |
| |
The area of the lesion spots is more than 2/3 |
Table 1 results of performance testing
As can be seen from the table 1, the chlorothalonil smoke agent provided by the invention has the advantages that the smoking time is delayed, the operator has enough time to leave after igniting the smoke agent pull wire, and the flame can be extinguished in time, so the safety in the use process is higher; in addition, the sugarcane residue powder is added into the ignition powder tube, so that the moisture resistance of the smoke agent is effectively improved, and the ignition rate of the smoke agent is still 100% after the smoke agent is stored for a long time; in addition, the modified magnesium hydroxide is added into the chlorothalonil, so that the diffusion and sedimentation speed of the gasified chlorothalonil are increased, and the pesticide effect of the gasified chlorothalonil on plant disease control is enhanced.
