Recently, when reporters visited some agricultural materials stores in Yunnan, they found that some of the glufosinate products had the words â€œexcept the root typeâ€ on the label of the product, and many of the enemy grass fast product labels had the words â€œrooted upâ€ and also marked â€œgrass and rootsâ€.
The reporter learned that glufosinate and diquat are fast-acting herbicides , not systemic herbicides. Therefore, it is unreasonable to publicize the functions of roots and roots. "This kind of propaganda is illegal. Even if the documents are complete, these words cannot be passed." The head of the domestic market for a pesticide manufacturer said.
The reporter interviewed a senior industry person on this issue. He pointed out that both Diquat and Glufosinate could not die. Anyone who has such propaganda on the label basically has problems. "The formal label is not written like this. â€
It is understood that both diquat and glufosinate are non-selective herbicides (ie, biocidal). Of these herbicides, only glyphosate is de-rooted because glyphosate is a systemic herbicide. In other words, only systemic herbicides can kill roots, and contact herbicides do not kill roots.
1. Popular science: selective herbicides and non-selective herbicides
Selective herbicides are herbicides that are effective in controlling weeds without affecting crops and killing only one or a certain type of weeds within certain environmental conditions and dosage ranges. Such as atrazine, 2 A 4 chlorine and so on.
Non-selective herbicides are also known as herbicides. It has harmful effects on weeds and crops. Herbicide such as paraquat, glyphosate, glufosinate and diquat is a non-selective herbicide.
2, science: systemic herbicides and contact herbicides
Systemic herbicide: It can be absorbed into weeds by roots, stems, leaves or buds of weeds after spraying, and transported to the whole plant in weeds, destroying the internal structure and physiology of weeds. Balanced so that weeds die, such herbicides are called systemic herbicides. For example, glyphosate can be applied to the weed plants by smearing on the leaves at the top of the weeds and transported down to the roots and stems to kill or inhibit the propagation of underground rhizomes. The systemic herbicide used as a soil treatment can be absorbed into the weed plants after being absorbed by the roots of the weeds. Systemic herbicides can control weeds that are annual and perennial.
The contact herbicide can not be transmitted or moved in the plant body, and can only kill the part of the plant directly contacting the drug, and does not damage the part not exposed to the drug, and the effect is relatively fast and the performance is intuitive. For example, 2 to 3 hours after the spraying of paraquat, the weed leaves begin to suffer discoloration.
If some glufosinate and diquat products really have root-killing effect, what do you say?
The above-mentioned industry sources said that if some glufosinate and diquat products really have root-killing function, it means that there are hidden formations with root-killing function, such as glyphosate, atrazine, and 2-methyl chloride. Wait.
Article 44 The new regulations, pesticide labels active ingredient contained in the pesticide-type, instructions on the label is inconsistent active ingredient, identified as fake pesticides.
False propaganda is involved if the label indicates that there is a root-killing function that is not actually available. According to Article 23 of the New Pesticide Management Regulations, pesticide production enterprises shall not arbitrarily change the label content of approved pesticides, and shall not mark the contents of false or misleading users in the label of pesticides.
According to Article 53 of the new pesticide management regulations, if the pesticide packaging, labeling and instructions produced by the pesticide production enterprise do not meet the requirements, the agricultural competent department of the local people's government at or above the county level shall order it to make corrections, confiscate the illegal income, illegally produced products and use. In the case of illegal production of raw materials, etc., the value of the illegally produced products is less than 10,000 yuan, and the fine is 10,000 yuan to 20,000 yuan, the value of the goods is more than 10,000 yuan, and the value of the goods is more than 2 times 5 If the refusal is not corrected or the circumstances are serious, the issuing authority shall revoke the pesticide production license and the corresponding pesticide registration certificate.
