What is Chlorpropham?

Part I: Introduction

 With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Chlorpropham which has developed particularly rapidly in recent years. Do you know about Chlorpropham?


The official answer: Chlorambucil is a plant growth regulator and herbicide used on grasses, alfalfa, lima, and broad beans, blueberries, sugar cane fruits, carrots, cranberries, quinoa, garlic, seed grass, onions, spinach, sugar beets, tomatoes, safflower, soybeans, mangosteen and woody seedlings. It is also used for the control of potato germination and smoking in tobacco. Chlorpropham is available in emulsifiable oils and liquid formulations.

Chlorpropham is approved for the treatment of potatoes for post-harvest preservation within the maximum residue limits for sprouting inhibitors in Germany. Chlorpropham products are approved as potato germination inhibitors in Germany, Austria, and Switzerland. Chlorpropham is approved for use as a plant regulator and herbicide on potatoes in the USA only.

What’s the application of Chlorpropham?

This product is both a plant growth regulator and herbicide. It is often used to inhibit the germination of potatoes during storage because of its ability to inhibit beta-amylase activity, inhibit plant RNA and protein synthesis, interfere with oxidative phosphorylation and photosynthesis, and disrupt cell division. It can also be used for flower and fruit thinning of fruit trees.

Meanwhile, chlorantraniliprole is a highly selective pre-or early post-emergence herbicide. It is absorbed by the shoot sheath of grass weeds, mainly by the roots of plants, but also by the leaves, and is conducted upward and downward in the body in both directions, effectively preventing and eliminating annual grass weeds and some broadleaf grasses in wheat, corn, alfalfa, sunflower, amaranth, sugar beet, soybean, rice, bean, carrot, spinach, lettuce, onion, pepper, and other crop fields.

For potato sprout suppression, after the harvest to wait for the natural healing of damage (about 14d or more) and before sprouting, the agent mixed with fine dry soil evenly scattered on potatoes, using a dose of 0.7% powder 1.4 ~ 2.1kg per ton of potatoes (active ingredient 9.8 ~ 14.7g); or 2.5% powder 400 ~ 600g (active ingredient 10 ~ 15g). The main weeds used for prevention and control are raw gram seedlings, barnyard grass, wild oats, early gram, multi-flowered ryegrass, flourishing wormwood, corn grass, shepherd’s purse, amaranth, oat grass, field codling moth, flat storage, horsetail, etc. Soil treatment before the seedlings after sowing of the crop, with 0.7% powder 157-425kg/hm2 alone or mixed, can prevent and eliminate sensitive weeds.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
