Potato insect pest aphid is extremely harmful, what medicine is used for potato insect pest aphid co

Potato early blight: Potato early blight can occur from seedling stage to adult plant stage, mainly affecting leaves, petioles and tubers. The affected leaves are left with black-brown, nearly circular necrotic lesions with obvious concentric rings, and in severe cases, the diseased leaves turn brown and die.

Petiole and stem damage Potato bacterial wilt is also one of the devastating diseases that can hit a large potato growing area and is a bacterial disease caused by Pseudomonas solanacear. Pseudomonas solanacearum generally overwinters in the soil as diseased residues.

Prevention and control methods: select disease-free seed potatoes, completely eliminate diseased potatoes before leaving seeds and cutting potatoes, and pay attention to the disinfection of knives when cutting pieces. Eliminate diseased plants in time when they are found.

Pay attention to the prevention and control of underground pests, implement crop rotation, and spray 58% methalene-manganese-zinc wettable powder 600 800 times liquid at the beginning of the disease, or 500 times liquid of 64% alum wettable powder, or 800 times liquid of Pulik water solution, sprayed once every 7 10 days, 2 3 times in a row.

Choose disease-free seed potatoes. The remaining tubers are strictly selected before germination before entering the cellar and after leaving the cellar, and the diseased tubers are eliminated. After germination, all those who do not germinate or germinate slowly, and the symptoms are all removed; When sowing in pieces or whole potatoes, strictly inspect and remove diseased potatoes and rotten potatoes.

Strengthen cultivation management, choose high-terrain, fertile and loose sandy loam land for planting, apply enough organic bottom fertilizer, increase phosphorus and potassium fertilizer, find diseased plants in the field and eliminate diseased residues in time and burn them in a centralized manner, and at the same time remove diseased potatoes and take them out of the field for deep burial.

Seed potatoes that are free of infectious diseases are carefully selected. Timely inspection in the field to find and remove infected plants. Use 1: every 5-10 days

Spray the Bordeaux liquid once at 2:40. If the prevention and control is not good, the soil-borne disease should be irrigated in time with the amount of 300-400 grams per mu of Tianlu sterilization king, and the spread of the disease can be controlled by irrigating twice at an interval of 3-5 days, and the fruit surface can be repaired.

Choose disease-resistant varieties, do not transport diseased potatoes from diseased areas, and eliminate diseased potatoes when sowing.

The medicine used for potato insect pest aphid control is the most common insecticide. For example, our most common 10% imidacloprid wettable powder 2000 times liquid, 40% dimethoate emulsion 1000 times liquid

The commonly used drugs for the control of aphids are as follows: 20 Halodimidamide, 20 Halodioxapyr pymetrozine, 50 Halodioxapyr, 40 Sulfoxapyr Ethyl spinosamad, 46 Fludimidamidine, 10 Imidacloprid, 50 Anti-aphid, Deltamethrin, 20 Deltamethrin, 50 Marathon, 1 Matrine, 25 Pymetrozine, Averrmectin, 50 Pyrazonil, Pyrethroid, 25 Cyanide Zinc EC, 50 Aphid Mist, 50 Octophthion, etc. You can choose to use it flexibly according to your needs and the type of crop.

1. 400 to 500 grams of 50% phosphine emulsion per mu, 3% phosphine particles to 2 kg, mixed in 50 kg of fine soil or sand, applied into the furrow during autumn ploughing or before sowing, raking or sowing soil, can effectively prevent and control the occurrence of underground pests. 2. In the peak period of adults, on crops or trees where pests are concentrated. Spray 100 times of 50% octan-sulfur emulsion, or 1000 times of 90% crystal trichlorfon, or 300 times of deltamethrin (trimethrin) emulsifiable concentrate, or 3000 times of 20% fenmethrin emulsifiable concentrate.

The commonly used pesticides for the prevention and control of grubs mainly include aldicarb, carbofuran, and phosphine. The commonly used drugs for the prevention and control of ground tigers are diaziphos emulsifiable concentrate or fenvalerate emulsifiable concentrate for surface spraying.

Summary. Spray aphids, use aphid pine, dimethoate, trichlorfon or 10% imidacloprid (aphid lice net) wettable powder per mu with 1 kg of water spray, or spray with 3000 4000 times of pyrethrin. Generally, the first spraying is carried out after the seedlings emerge, and then every 10 to 20 days, according to the number of aphids.

Potato insect pest aphid is extremely harmful, what medicine is used for potato insect pest aphid control?

Can potato ground aphids use halodioxapyr?

Spray aphids, aphid pine, Le Ku cryptocarp, trichlorfon or 10% imidacloprid (aphid lice net) wettable powder per mu with 1 kg of digging water spray, or spray with 3000 4000 times of pyrethrin. Generally, the first spraying of the nucleus is carried out after the emergence of the seedlings, and then every 10 20 days, according to the number of aphids.

After using sulfoxapyr once, it had no effect.

If there is trichlorfon, use it.

It's the same as nothing. If not, you have to change the dressing.

Use aphidpine, dimethoate, trichlorfon or 10% pyridoxine (aphid kill lice net) wettable powder with 1 kg of water per mu, or spray with 3000 4000 times of pyrethrin containing jingjing. Generally, the first spraying is carried out after the seedlings emerge, and then every 10 to 20 days, according to the number of aphids.

You can buy some pesticides and mix them in the soil fingers of potatoes, you can hang some silver gray film or mold bucket with silver-gray film strips in the potato field, and you can also put some sweet and sour liquid in the land, which can play a role in removing potato aphids.

The simplest and most effective way is to directly talk about spraying the corresponding pesticides, so that the harm of aphids can be directly solved. Moreover, it is necessary to choose potatoes that have high disease resistance for planting, and to fertilize in time to help potatoes grow healthily, and to keep the soil moist, so that potatoes have a good growth environment, so that the quality and yield of potatoes can be effectively improved.

1. Take advantage of the natural conditions of cold, windy and humid.

The maximum temperature of aphid activity is 25 degrees, and the number of aphid breeding generations is greatly reduced at temperatures below 15 degrees. At the same time, it can prevent aphids from taking off and Zina from spreading the virus. Therefore, cold conditions are not suitable for aphid breeding, feeding, migration and transmission of viruses, but such conditions are very suitable for potato growth.

2. Seed potato fields should be kept away from virus* bean fields.

According to the migration and transmission distance of aphids, the original soybean seed and first-class seed potato breeding base should be at least 2000 meters away from the soybean production field and other solanaceae fields.

3. Avoid the peak of aphid migration.

According to the migration and transmission time of winged aphids, the appropriate sowing and harvesting dates for soybean ackers can be arranged, such as early sowing or staggered sowing, which can reduce aphid poisoning.

Take advantage of the yellowing properties of aphids. Physically trap aphids in the field with yellow adhesive boards. The attachment of aphids to silver-gray in the hall of Lidepa.

Hang silver-gray film or silver-gray film strips (10 15 cm wide) in the field, with 75 kg of film per hectare or with film strips 225 kg to repel aphids. Use sweet and sour basins or frequency-vibration insecticidal lamps.

Set up sweet and sour liquid basins or frequency vibration insecticidal lamps in the field to trap and kill pests such as tigers and beetles, reduce the degree of insect pests and reduce wounds, and prepare coarse to reduce the way of disease infection.

1. Ground tiger, noisy belongs to the family of noctuidae, the adult mouthparts are developed, polyphagous crop pests, there are many types, and there are more than 10 kinds of agricultural crops that cause harm;

2. Aphids, also known as greasy insects and honey worms, are a class of herbivorous insects, including all members of the general family Aphids;
