Disease control of Ribes robusta
The pests that harm Ribes robusta are: oyster scale and polysaccharide yellow borer. In case of oyster scale, 400 times of 95% acaricidal emulsion can be sprayed on the branches of plants during the crawling period of nymphs from mid-May to mid-June, and attention should be paid to the protection and utilization of natural enemies such as Mongolian ladybug. If there is Pleistocene yellow moth, it can be trapped and killed by black light, and 25% suspension concentrate can be sprayed at the larval stage 1000 times.
