What are the particularities about the cross use of pesticides?

In our country is a strong country in crop planting, and the indispensable use of pesticides in crop planting is the use of pesticides, but some friends because of unreasonable operation methods have led to the abuse of pesticides, below we give us an interpretation of the impact of pesticide abuse and how to prevent pesticide abuse. <>

What harm is pesticide abuse.

1. The abuse of pesticides leads to drug resistance and reduces the service life of equipment, 2. The abuse of pesticides leads to a continuous increase in the amount of use, resulting in a vicious circle and <>

3. The abuse of pesticides leads to the residues of agricultural products exceeding the standard to insects (beneficial insects), fish, bees, and birds, causing immediate or indirect harm and destroying biological diversity, 4. The abuse of pesticides leads to fertilizer damage, damage to the production and manufacturing of food crops, and harms people's physical and mental health, 5. The abuse of pesticides leads to water ingress into the natural environment, environmental pollution, etc.

What are the cross-application methods of pesticides in facility vegetables? Authoritative experts believe that there are four common ways of pesticide crossing:

1. Cross-application of microbial pesticides, mineral-derived pesticides, and organic chemical pesticides. For example, in the production and manufacturing of Chinese cabbage to prevent cabbage insects, BT solvent, rotenin, chlorpyramide, and trichlorfon can be cross-applied.

2. Cross-application of protective film and systemic agent. For example, for downy mildew in vegetables and fruits, the pesticides to be used before the disease and after the gradual onset of the disease should be different, and must be cross-applied.

3. Cross-application of spray and fumigant. In order to ensure the normal manufacture of vegetables, we should be good at using the characteristics of good sealing of greenhouses and plastic sheds.

4. Cross-application of other forms of agents. When pesticides are applied, the leaf stem solution of the agent is cross-applied with the soil layer; Insecticides that do not have ovicidal activity are cross-applied with ovicides.

The effective mixed application of pesticides can save human resources and time, and can also achieve the purpose of concurrent treatment, quality and efficiency improvement, and drug resistance.

But in addition, Zou Zhirong reminded many growers that pesticide mixing should be created on the basis that the original physical properties will not be destroyed after mixing, and the control effect will affect each other or gradually improve. When mixing pesticides, it should be noted that microbial pesticides of edible fungi and organic chemical pesticides and fungicides should not be mixed; Systemic and pyrethroid insecticides, as well as dithiocarbamate pesticide fungicides, should not be mixed with alkaline pesticides; Pesticides with similar characteristics should not be mixed.

We must pay attention to the collocation of pesticides, we must pay attention to the time of spraying, we must spray reasonably, and we must determine the spraying scheme according to the actual situation, which is generally cross-used by biological pesticides, organic pesticides and mineral pesticides.

It is necessary to pay attention to the characteristics of pesticides, avoid pesticide damage when cross-use, do not let them have chemical reactions, and do not produce toxic gases, and choose relatively safe ones.

First of all, we must pay attention to the appropriate time, and then when we use it cross-use, we must pay attention to each important ingredient, we must not produce a particularly serious chemical reaction, we must pay attention to the rational use of drugs, and we also need to pay attention to reading the instructions.

It is necessary to pay attention to the time of cross-use, but also to the amount of cross-use, but also to pay attention to the scope of cross-use, but also to pay attention to the way of cross-use, and also pay attention to the drug combination of cross-use.
