Comprehensive Prevention and Cure Techniques of Three Kinds of Sugarcane Pests

During the whole growth period, sugar cane suffers from root pests, leaf pests, and stem pests. If these three types of pests do not pay attention to prevention and control, the growth of sugarcane and the high quality and high yield of the sugarcane stems are very large. influences. The key technologies for comprehensive prevention and control of these three types of pests are described below for reference by readers.

I. Prevention and control of root pests

The root pests are underground pests, and they mainly include golden needles, cockroaches, beetles, termites, and crickets. Prevention and control of such pests should first be implemented with paddy crop rotation and chemical treatment of seedlings in order to reduce the source of insects and transplanted with insects. Secondly, we should combine the sowing and application of basal fertilizer with 3.6% of insecticidal double granules, or 5% of butylthiocarbamate, or 5% of granules of 3-4 kilograms of power to eliminate pests that have been active in the ground. Thirdly, when the field population density is 2% or more, the pest density in the field should be combined with cultivating soil in a timely manner. Generally, 2.5% of the enemy should kill 2000 times of liquid per acre, or use 90% of trichlorfon 800-1000 times of liquid. , Or 50% of phoxim EC 1000-1500 times, or 50% diazinon EC 1000-1500 times 60 kg alternating spray. In addition, when pests occur, that is, during the period of adult emergence, Jiaduo frequency-vibration insecticidal lamps should be used to trap and kill adults.

Second, the prevention and treatment of leaf pests

Mainly sucking insect pests, there are cotton aphid, astragalus, thrips, sugarcane planthoppers, sugarcane leafhoppers, mealybugs, cockroaches, cockroaches and so on. The method of prevention and control of such pests is mainly chemical control, that is, on the basis of transplanting with drugs or treatment of seedlings with pesticides, it is necessary to strengthen the use of pesticides in each occurrence period. The appropriate period for the control of pesticides on leaf pests is the initial stage of occurrence, generally per mu. It can be sprayed with 10% imidacloprid, or 40% Locuspen or 80% dichlorvos 1000-2000 times liquid 60 kg. The first prevention and treatment of Mianjiao and Huangqi is from late June to mid-July, and the second prevention and treatment is from mid-August to early September. For pests such as thrips, sugarcane planthoppers, sugarcane leafhoppers, mealybugs, and cockroaches, the timing of drug use should be determined based on the occurrence of insect damage.

Third, the prevention and treatment of stem pests

Mainly for borer pests, there are two points, larvae, big pupa, yellow peony, white peony, Taiwan rice pods and so on. Control methods: First, according to the density of insect population in the field, combined with cultivating soil in the cultivator, generally use 3.6% insecticidal double granule per acre, or 5% butyl thiocarbacarb, or 5% granules such as 3-4 Kilograms are concentrated in the crotch. The second is to seize the use of 90% of trichlorfon crystals per acre in the ant-flood period 500 times, or 80% of dichlorvos 800-1000 times in liquid spray of 60 kilograms, especially in the case of damage, if the heart leaves show The characteristics of the mosaic ring can be focused on spraying and killing in time.

A Microscope is an instrument used to see objects that are too small to be seen by the naked eye. Microscopy is the science of investigating small objects and structures using such an instrument. Microscopic means invisible to the eye unless aided by a microscope.

There are many types of microscopes, and they may be grouped in different ways. One way is to describe the way the instruments interact with a sample to create images, either by sending a beam of light or electrons to a sample in its optical path, or by scanning across, and a short distance from the surface of a sample using a probe. The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both the transmission electron microscope and the scanning electron microscope) and the various types of scanning probe microscopes.
