Problems solved by technology

[0002] In recent years, due to the rise of intensive planting patterns, the phenomenon of continuous cropping on the same land has become serious. With the extension of planting time, soil-borne diseases have occurred seriously, such as cucumber wilt, tomato wilt, pepper blight, root-knot nematode, etc. The harm of pests and diseases and their control have caused a direct decline in farmers' income. On the other hand, due to the long-term use of a single type of pesticide and the adaptive variation of Phytophthora capsici to chemical pesticides, the control effect of some pesticides has decreased, which has brought difficulties to the control. Some pesticide residues are large, which will have a certain impact on the soil and have negative effects on crops. Therefore, screening out new effective low-residue fungicides is of great significance for reducing the losses caused by pepper blight.

Embodiment 1

[0023] A soil disinfectant for preventing and treating Phytophthora capsici. The raw material components of the soil disinfectant include urea peroxide and biogas slurry. The mass ratio of urea peroxide to biogas slurry is 1:99. The biogas slurry is chicken manure biogas slurry. The EC value of biogas slurry is 3mS·cm -1 .

[0024] The preparation steps are as follows:

[0025] Dilute chicken manure biogas slurry to its EC value of 3mS cm -1 , to obtain biogas slurry dilution, then weigh urea peroxide and biogas slurry dilution in proportion, dissolve urea peroxide in the biogas slurry dilution and mix evenly to obtain a soil disinfectant for preventing and treating Phytophthora capsici.

[0026] Antibacterial test

[0027] The celery waste is beaten and processed, and 1 g of the slurry is weighed and put into a petri dish for processing. Respectively with sterile water 20ml as control group, 1% soil disinfectant of the present invention 20ml, after soaking 5min, prepare d...

Embodiment 3

[0036] The soil disinfectant of the prevention and treatment of capsicum phytophthora of application embodiment 1 prevents and controls the method for capsicum bacterium and actinomycetes,

[0037] On September 12, 2013, the pepper seeds were sown in the seedling tray. Within one week before the pepper seedlings were planted, the soil disinfectant for preventing and controlling Phytophthora capsici was sprayed on the surface of the soil to be planted twice, each time each pepper seedling was sprayed The amount is 5mL, and it is applied once after the seedlings are planted slowly, 5mL per plant. In order to reflect the control effect, when the seedlings reached 60 days old, 1 mL / plant of Phytophthora capsici sporangia suspension was inoculated by root irrigation method, and the control effect on Phytophthora capsici was observed.

[0038] After the inoculation, the pepper seedlings were subjected to normal water and fertilizer management, and a certain temperature and humidity ...

Abstract

The invention relates to soil disinfectant and a method for preventing and treating phytophthora capsici. A raw material of the soil disinfectant comprises the following components: urea-hydrogen peroxide and biogas slurry. The mass ratio of the urea-hydrogen peroxide to biogas slurry is (1-5): (95-99). By the soil disinfectant, the phytophthora capsici in soil can be killed, crops and seedlings can be prevented from being threatened by soil-borne diseases, certain nutrient substances are provided for plant growth, and residues are avoided.

Description

technical field [0001] The invention relates to a soil disinfectant for preventing and treating Phytophthora capsici and a control method thereof, belonging to the technical field of crop control. Background technique [0002] In recent years, due to the rise of intensive planting patterns, the phenomenon of continuous cropping on the same land has become serious. With the extension of planting time, soil-borne diseases have occurred seriously, such as cucumber wilt, tomato wilt, pepper blight, root-knot nematode, etc. The harm of pests and diseases and their control have caused a direct decline in farmers’ income. On the other hand, due to the long-term use of a single type of pesticide and the adaptive variation of Phytophthora capsici to chemical pesticides, the control effect of some pesticides has decreased, which has brought difficulties to the control. Some pesticide residues are relatively large, which will have a certain impact on the soil and have negative effects ...
