Medicament and method for preventing and controlling phytophthora cactorum of palms

Abstract

The invention discloses a medicament for preventing and controlling phytophthora cactorum of palms, which comprises sandofan and nitrogen, phosphorus and potassium elements, wherein the using concentration of the sandofan is 1 to 5 percent; and the nitrogen, phosphorus and potassium elements are effective components of carbamide and monopotassium phosphate, and the using concentration of the carbamide and the monopotassium phosphate is 0.1 to 1 percent. A method comprises the following steps: a, preparing the medicament, namely preparing sandofan wettable powder with the purity of 64 percent into 1 to 2 percent solution, and adding the carbamide and the monopotassium phosphate to prepare 0.2 percent medicament solution for preventing and controlling the phytophthora cactorum of the palms;b, well dressing a proper amount of coconut residuum on bases of the plants with plastic films; and c, adding the medicament solution prepared in the step a into the coconut residuum with an injectorin a dosage of 50-100ml per plant. The invention aims to overcome the defects of the prior art to provide the medicament for effectively preventing and controlling the phytophthora cactorum of the palms, and the method with simple operation and capable of effectively preventing and controlling the phytophthora cactorum of the palms.

Description

technical field [0001] The invention relates to a medicament for preventing and treating palm plant phytophthora and a method for using the medicament to prevent and control palm plant phytophthora. Background technique [0002] Palm plant Phytophthora is common in palm planting areas in my country, and it is one of the most harmful soil-borne diseases. The disease spreads quickly. Once Phytophthora is found, it is difficult to achieve better control effect with conventional spraying. It is necessary to adopt new and effective control methods. [0003] Palm plant Phytophthora is caused by Phytophthora fungus, mainly manifested as heart rot, so it is also called heart rot or bud rot. According to statistics, there are currently reports of this disease in more than 20 countries. In the United States, California, Florida and Hawaii are the most serious areas. Phytophthora has a wide range of hosts and can attack at least 25 species of palms. Coconut, palm bamboo, Washington ...

AI Technical Summary

Problems solved by technology

[0004] At present, domestic and foreign prevention and treatment of Phytophthora mainly adopts spraying and root irrigation, although it can play a certain role, but the control effect is relatively poor. Operation requires specific spray equipment, which is easy to cause pollution to the environment, and root irrigation and control is also likely to cause pollution to soil and water sources

In addition, the existing medicaments used to prevent and control Phytophthora are relatively poor in effect and have a relatively short validity period
