Integral prevention and control method for dark plum pest diseases

Abstract

The invention provides an integral prevention and control method for dark plum pest diseases and belongs to the field of fruit tree pest disease prevention and treatment. The integrated assembly is carried out on five prevention and treatment measures including pest condition monitoring, agricultural prevention and treatment, physical prevention and treatment, biological prevention and treatment and chemical prevention and treatment by aiming at the four phenological periods including the sprouting and flowering period, the young sprout growth and fruit development period, the fruit harvesting and nutrition recovering period and the leaf falling and dormancy period in the annual growth process of the dark plum, the respective defects in the use process are overcome, the cooperated pest disease control effect is sufficiently realized, and the integral prevention and control measures applicable to the pest diseases in each phonological period are provided. The method provided by the invention can be used for effectively controlling the occurrence and the harm of the major pest diseases of the dark plum, the harm of the pest diseases of the dark plum is controlled in an economic threshold value range, the use times and the consumption of pesticide are obviously reduced, the important significance is realized on the public-hazard-free dark plum production and the environment protection, and the harmless production of the dark plum and the virtuous cycle of the natural ecological system are realized.

Description

technical field [0001] The invention relates to a method for comprehensive prevention and control of black plum diseases and insect pests, and belongs to the field of prevention and control of fruit tree diseases and insect pests.

Problems solved by technology

Agricultural control: reduce pest damage by selecting insect-resistant varieties and strengthening cultivation management; the advantages are convenient, economical, and preventive; the disadvantage is that the existing pests cannot be controlled

Physical control: use methods such as manual hunting, whitening or bandaging of tree trunks, color boards (yellow boards, blue boards, etc.), attractants, sugar solution and light trapping to reduce; advantages: the most direct and effective, without destroying the ecological balance, without Produce 3R consequences, disadvantages: it is necessary to better grasp the occurrence dynamics of diseases and insect pests, select the appropriate period for prevention and control, and require more manpower and material resources, involving slightly higher costs, such as manual hunting and insect control nets, etc.

Biological control: use natural enemies birds and insects, fungi and bacteria, pathogenic nematodes and other biological resources to control the population of diseases and i
