Underground pests should be sprayed or irrigated with 50% phoxanthion EC 1000 times or 40% dimethoate EC 1000 times.

There are insects on taro leaves, which can be sprayed to kill insects. The effect is relatively good. Also listen to the use of trichlorfon. Some bugs can also be killed with fat and smelly water.

There are a lot of insects in taro leaves, what kind of medicine is used?

Hello: There are many insects in taro leaves, and the control methods are as follows Aphids. Adults and nymphs suck the juice on the back of the leaves or young leaves, so that the leaves are curled and deformed, the growth is poor, and the virus disease is transmitted, and in severe cases, the leaves are covered with black mold.

Control methods: dimethoate and imidacloprid pesticides can be sprayed. Spodoptera litura.

The larvae feed on leaves, and in severe cases, only leaf veins remain. Generally, kung fu or Lesben, imidacloprid and Ruijinte are sprayed before the larvae are 3 years old, and comprehensive control should be considered with medication. For example, pyridaprid plus avermectin can prevent pests such as taro aphid and Spodoptera litura.

Underground pests. Combined with two heavy fertilization applications, phosphine, milel or trichlorfon can be used for control. Spider mites.

Spray 1500 times monocrotophos or 800 times 40% dimethoate or 800 times dicofol. The main pests that harm taro are aphids, Spodoptera litura, underground pests, etc. The main insect pests are leaf moths, red spiders, and aphids.

The main pests are aphids and red spiders, which can be controlled with imidacloprid oxidation. The main insect pests of taro are aphids, underground pests, red spiders, etc. The main insect pests are aphids and Spodoptera litura, which can be controlled with avermectin.

Aphids, spider mites, underground pests, Spodoptera litura. Drug control, dimethoate, imidacloprid, trichlorfon, avermectin. There are mainly sedan aphids and underground pests Spodoptera litura, which can be controlled by imidacloprid oxidation dimethoate.

How to control common pests and diseases of taro.

1. Spodoptera litura.

The common insect pest of taro is Spodoptera litura, which can be sprayed with diluted chlorantraniliprole to avoid pest reproduction, if Spodoptera liturae have appeared on the taro, it should be sprayed with trichlorfon or quick killing agent in time, and the larvae will be killed with medicine in the morning and evening.

2. Taro blight.

In the process of growth, taro is prone to taro blight, affecting the growth of leaves and bulbs, because the blight mostly occurs in high temperature and high humidity weather, so the rainy season and summer should regularly spray mancozeb, methacryl and other agents for taro to avoid the breeding and spread of germs.

3. Soft rot.

After taro suffers from soft rot, it will lead to water-stained spots on the leaves, and continue to expand over time, eventually leading to soft rot of plant rhizomes, when preventing and controlling soft rot, it is necessary to apply organic fertilizer to taro to improve disease resistance, once the diseased plant is found, it should be eradicated in time, and sprayed with copper oxychloride suspension every 10 days.

Taro leaves are bitten, mainly caused by the larvae of the lepidopteran family Spodoptera exigua, at present, it is mainly Spodoptera exiguae and Spodoptera litura, both of which are omnivorous and gluttonous pests, and the control should be before the larvae 3 orders, at this time the pest resistance is relatively small, and it should be noted that the time of noctuidae should be selected in the evening, and the agent can be selected as Kane or American spray.

The insect species is too strong, what kind of insect are you talking about? There is no determination of this factor, only the pure of selling drugs. There is no panacea that can destroy all insects in the world. The omnipotence preached may actually be nothing.

Summary. Herbicides such as paraquat or broadleaf herbicides such as chlorofluoropyroxyacetic acid (chlorofluoropyroxyacetic acid) can be used for repeated spraying (repeated when new young leaves have grown after the leaves have withered).

Herbicides such as paraquat, acacia or broad-leaved herbicides such as chlorofluoropyroxyacetic acid (chlorofluoropyroxyacetic acid) can be used for repeated multi-basis differential spraying (repeated when new young leaves have grown after the leaves have withered).

Ethoxyflufen is a selective contact soil treatment and a herbicide that has the effect of post-emergence stem and leaf treatment. Use the drug after sowing and before seedling or sowing (cutting). It is recommended to use 40 50 ml of 24% ethoxyfluorfen emulsifiable concentrate per mu, mixed with 60 liters of water, evenly sprayed on the soil surface, and can be equipped with hidden prevention and control of barnyard grass, Qianjinzi, ox tendon grass, dogtail grass, hard grass, Kanmai Niang, stick head grass, early maturing grass, purslane, iron amaranth, amaranth, quinoa, Po regret selling stove Pona, knotweed, etc., wild taro A variety of bi-dressed annual weeds, the control effect of perennial weeds is poor.

When spraying, it is required to be uniform and thoughtful, and the dosage should be accurate.

In addition, pesticides can be harmful to human health and should therefore be avoided during food processing. If pesticides need to be used during storage or transportation, the taro should be thoroughly washed before soaking the seeds.

Hello, taro soaking is to promote taro germination, increase growth rate and yield. Pesticides are used to kill or control pests to prevent them from causing harm to plants. The use of pesticides in the taro soaking process is not recommended as the pesticides may remain in the taro and have a negative impact on human health.

In addition, the taro dipping species themselves do not need to use insecticides, because the seedlings of taro germination are not susceptible to insect infestation.

Summary. At the same time as the use of the drug, streptomycin is added, and the farmhouse fertilizer that has been rotted by the rotten stalk can also be applied with phosphine or trichlorfon, and the dosage is used according to the conventional custom. The amount and frequency of top dressing should be based on the field nutrition diagnosis, the base fertilizer is sufficient, and the plots with good fertility can be fertilized appropriately.

The taro I planted was eaten by insects, how to solve it if the medicine didn't work?

Add streptomycin at the same time as the medicated bridge, and also use phosphine or trichlorfon to apply farmhouse fertilizer that has been cooked by rotting stalks, and use the usual dosage. The amount and frequency of top dressing should be based on the field nutrition diagnosis, the base fertilizer is sufficient, and the plots with good fertility can be fertilized in an appropriate amount.

Dear, you can only add these in medicine.

There is no way to remove the disease residues in the field in time, and you can also use 600 800 times of 70 Dysen zinc wettable powder, or 60 carbendazim wettable powder taro wheel to tell the head of the base.

Using phoxanthan or trichlorfon will do.
