Problems solved by technology

Relatively low concentration of active ingredient leads to increased transportation costs, increased disposal difficulties and reduced efficiency
Furthermore, once trichloropyridine is used, it causes severe damage to the atmosphere, leading to adverse environmental effects, loss of efficacy of the product through loss of potency, and unpleasant odour.

[0264] It should be understood that the following examples are provided by way of illustration only and nothing therein should be considered limiting.

example 1

[0265] Example 1. Reducing the Volatility of Trichloromethylpyridine / Polyanionic Polymer Salts.

[0266] The three materials were placed on a thermal balance at 100° C. and their weights were observed every minute for 10 minutes as a percentage of the original weight. The materials are:

[0267] 1. Pure trichloromethylpyridine,

[0268] 2.25% w / w trichloromethylpyridine solution in sulfolane, and

[0269] 3. 25% solution of chloridinium salt with equimolar amount (acid based) of maleic acid-itaconic acid copolymer also in sulfolane (trichloromethylpyridine / polyanionic polymer salt).

[0270] The weight loss data in Tables 2-3 show that polyanionic polymer salts of trichloropicoline, both as a solution and as free trichloropicoline, exhibit Significantly reduced trichloromethylpyridine loss rate. The data show that trichloromethylpyridine volatilization was reduced by 10%-30% when used in salt form compared to untreated. Thus, the disclosed trichloromethylpyridinium salts ...

Abstract

The presently disclosed subject matter is directed to nitrapyrin complexes and syntheses thereof finding particular utility in agricultural uses, e.g., directly applied to soil, or in combination with fertilizers to increase nutrient uptake and to inhibit nitrification and urease hydrolysis. More particularly, the subject matter is directed to nitrapyrin complexes, preferably containing specific types of carboxylic and sulfonate repeat units. Other uses of the nitrapyrin complexes and compositions containing nitrapyrin complexes are also disclosed.

Description

technical field [0001] The presently disclosed subject matter relates to the discovery of trichloromethylpyridine complexes with polyanions and their synthesis with specific utility in agricultural applications to increase nutrient uptake and inhibit nitrification. Background technique [0002] Nitrogen fertilizers added to soil are readily transformed by a variety of biological and chemical processes including nitrification, leaching and evaporation. Most transformation procedures are undesirable because they reduce the level of nitrogen available to the target plant. The reduction in available nitrogen requires the addition of more nitrogen-rich fertilizers to compensate for the loss of agriculturally active nitrogen available to plants. Nitrification is the process by which certain ubiquitous soil bacteria metabolize nitrogen in the form of ammonium in the soil, converting the nitrogen into nitrite and nitrate forms that are more readily passed through leaching via denit...
